December 26, 2025 | Leave a comment A Complete Guide to why Core Transit’s WireGuard IP Transit Service is so incredibly awesome for you lab Bypassing CG-NAT with style – a detailed technical walkthrough The Problem: CG-NAT Hell If you’re reading this, you probably know the pain. Your ISP puts you behind Carrier-Grade NAT (CG-NAT), which means: No port forwarding No hosting servers at home No running services accessible from the internet Dynamic, shared IP addresses I was stuck behind CG-NAT on my home internet connection and needed real, routable public IP addresses for my homelab. After researching options (VPS with reverse proxy, Cloudflare Tunnel, etc.), I discovered Core Transit – a service that provides actual public IPv4 and IPv6 blocks via WireGuard tunnel. The Solution: Core Transit Core Transit offers WireGuard-based IP transit. You get: A dedicated public IPv4 block (I got a /28 = 14 usable IPs) A public IPv6 block (I got a /60 = 16x /64 subnets) Traffic routed through their infrastructure via encrypted WireGuard tunnel Works through any NAT, including CG-NAT This guide documents every step I took to get it working on a Linux gateway/router. Prerequisites Hardware A Linux server/router with at least 2 network interfaces One interface for WAN (internet connectivity) One interface for your DMZ/public-facing network Software Linux with kernel 5.6+ (WireGuard built-in) or wireguard-tools Open vSwitch (optional, for bridge management) nftables or iptables for firewall dnsmasq (optional, for DHCP on DMZ) From Core Transit After signing up, you’ll receive: Your allocated IPv4 block (e.g., 203.0.113.176/28) Your allocated IPv6 block (e.g., 2001:db8:abcd:1e0::/60) Tunnel endpoint IP and port Tunnel point-to-point addresses Their WireGuard public key Your WireGuard keypair (or generate your own) Network Architecture Here’s what we’re building: INTERNET │ ┌─────────────┴─────────────┐ │ CORE TRANSIT POP │ │ (Your tunnel endpoint) │ │ │ │ Routes to you: │ │ • YOUR_IPV4_BLOCK/28 │ │ • YOUR_IPV6_BLOCK/60 │ └─────────────┬─────────────┘ │ WireGuard Tunnel (ChaCha20-Poly1305) │ ══════════════════════════════════╪════════════════════ YOUR NETWORK │ │ ┌─────────────┴─────────────┐ │ YOUR ISP GATEWAY │ │ (NAT / CG-NAT / etc) │ └─────────────┬─────────────┘ │ ┌─────────────────────┴─────────────────────┐ │ YOUR LINUX GATEWAY │ │ │ │ ┌───────────┐ │ │ │ eth-wan │ WAN interface (DHCP) │ │ │ │ Default route to ISP │ │ └─────┬─────┘ │ │ │ │ │ ┌─────┴─────┐ ┌──────────────────┐ │ │ │wg-transit │ │ br-dmz │ │ │ │ │ │ (OVS Bridge) │ │ │ │Tunnel IPs │ │ │ │ │ │ │ │ Public Gateway │ │ │ │ │ │ YOUR_BLOCK.177 │ │ │ └───────────┘ └────────┬─────────┘ │ │ │ │ │ Policy Routing │ │ │ (Table 100) │ │ │ ┌─────────┘ │ │ │ │ │ ┌────┴────┐ │ │ │ eth-dmz │ Physical port │ │ └────┬────┘ │ └───────────────────│───────────────────────┘ │ DMZ Network │ ┌───────────┴───────────┐ │ │ ┌──────┴──────┐ ┌──────┴──────┐ │ Server │ │ Server │ │ .178 │ │ .179 │ └─────────────┘ └─────────────┘ Key Concepts WireGuard Tunnel: Encrypted connection to Core Transit carrying your public IP traffic Policy Routing: Traffic FROM your public IPs routes through the tunnel, not your normal ISP DMZ Bridge: Internal network where you assign public IPs to servers Firewall: Protect your gateway from the public internet Step 1: Install WireGuard Tools Ubuntu/Debian apt update apt install wireguard-tools RHEL/CentOS/Rocky dnf install wireguard-tools Verify Installation # Check if WireGuard kernel module is available modprobe wireguard lsmod | grep wireguard # Check wg command exists which wg wg --version What this does: Installs the userspace tools (wg, wg-quick) needed to configure WireGuard interfaces. Modern kernels (5.6+) have WireGuard built-in; older kernels may need the DKMS module. Step 2: Generate WireGuard Keys (If Not Provided) If Core Transit didn’t generate keys for you: # Generate private key wg genkey > /etc/wireguard/private.key chmod 600 /etc/wireguard/private.key # Derive public key from private key cat /etc/wireguard/private.key | wg pubkey > /etc/wireguard/public.key # View your public key (send this to Core Transit) cat /etc/wireguard/public.key What this does: Creates a cryptographic keypair. The private key stays on your server (never share it!). The public key gets registered with Core Transit so they can authenticate your tunnel. Step 3: Create WireGuard Configuration Create the configuration file: nano /etc/wireguard/wg-coretransit.conf Paste the following (replace placeholders with your actual values): # Core Transit WireGuard Tunnel Configuration # Replace all YOUR_* values with actual values from Core Transit [Interface] # Your private key (keep this secret!) PrivateKey = YOUR_PRIVATE_KEY_HERE # Tunnel point-to-point addresses (provided by Core Transit) # These are the IPs assigned to YOUR end of the tunnel Address = YOUR_TUNNEL_IPV4/31, YOUR_TUNNEL_IPV6/64 # MTU - Start with 1420, we may need to lower this later MTU = 1420 # Use a separate routing table for policy routing Table = 100 # Policy routing rules - traffic FROM your public block uses table 100 PostUp = ip rule add from YOUR_IPV4_BLOCK/28 table 100 priority 5 PostUp = ip -6 rule add from YOUR_IPV6_BLOCK/60 table 100 priority 5 PostDown = ip rule del from YOUR_IPV4_BLOCK/28 table 100 priority 5 PostDown = ip -6 rule del from YOUR_IPV6_BLOCK/60 table 100 priority 5 [Peer] # Core Transit's public key (provided by them) PublicKey = CORETRANSIT_PUBLIC_KEY_HERE # Core Transit endpoint (IP:port provided by them) Endpoint = CORETRANSIT_ENDPOINT_IP:PORT # Route ALL traffic through tunnel (for table 100 only) AllowedIPs = 0.0.0.0/0, ::/0 # Keep tunnel alive through NAT PersistentKeepalive = 25 Example with Placeholder Values [Interface] PrivateKey = aBcDeFgHiJkLmNoPqRsTuVwXyZ1234567890abcdefg= Address = 203.0.113.253/31, 2001:db8:1000:23::2/64 MTU = 1420 Table = 100 PostUp = ip rule add from 203.0.113.176/28 table 100 priority 5 PostUp = ip -6 rule add from 2001:db8:abcd:1e0::/60 table 100 priority 5 PostDown = ip rule del from 203.0.113.176/28 table 100 priority 5 PostDown = ip -6 rule del from 2001:db8:abcd:1e0::/60 table 100 priority 5 [Peer] PublicKey = XyZ0987654321AbCdEfGhIjKlMnOpQrStUvWxYz1234= Endpoint = 198.51.100.1:10305 AllowedIPs = 0.0.0.0/0, ::/0 PersistentKeepalive = 25 What this does: PrivateKey: Authenticates your side of the tunnel Address: IPs assigned to the tunnel interface itself (point-to-point link) MTU: Maximum packet size (more on this later) Table = 100: Routes learned from this tunnel go into routing table 100, not main PostUp/PostDown: Policy routing rules that send traffic FROM your public IPs through the tunnel PublicKey: Core Transit’s identity Endpoint: Where to send encrypted packets AllowedIPs = 0.0.0.0/0, ::/0: Accept any destination (full tunnel for table 100) PersistentKeepalive: Keeps NAT mappings alive Set proper permissions: chmod 600 /etc/wireguard/wg-coretransit.conf Step 4: Enable IP Forwarding Your gateway needs to forward packets between interfaces: # Enable immediately sysctl -w net.ipv4.ip_forward=1 sysctl -w net.ipv6.conf.all.forwarding=1 # Make persistent across reboots echo "net.ipv4.ip_forward=1" >> /etc/sysctl.conf echo "net.ipv6.conf.all.forwarding=1" >> /etc/sysctl.conf What this does: Allows your Linux box to act as a router, forwarding packets between the tunnel interface, DMZ interface, and WAN interface. Step 5: Bring Up the WireGuard Tunnel # Start the tunnel wg-quick up wg-coretransit # Verify it's running wg show wg-coretransit Expected output: interface: wg-coretransit public key: YOUR_PUBLIC_KEY private key: (hidden) listening port: 51820 peer: CORETRANSIT_PUBLIC_KEY endpoint: 198.51.100.1:10305 allowed ips: 0.0.0.0/0, ::/0 latest handshake: 5 seconds ago <-- THIS IS THE KEY LINE transfer: 1.23 MiB received, 456.78 KiB sent persistent keepalive: every 25 seconds Success indicator: You should see “latest handshake: X seconds ago”. If this never appears, the tunnel isn’t establishing. Test Tunnel Connectivity # Ping Core Transit's tunnel IP (their side of the point-to-point link) # This IP is typically YOUR_TUNNEL_IP - 1 or as provided by Core Transit ping YOUR_CORETRANSIT_TUNNEL_PEER_IP # Example: ping 203.0.113.252 If this works, your tunnel is up! Step 6: Create the DMZ Bridge (Optional but Recommended) Using Open vSwitch to create a bridge for your public-facing network: # Install OVS if not present apt install openvswitch-switch # Create the bridge ovs-vsctl add-br br-dmz # Add your physical DMZ interface to the bridge # Replace eth-dmz with your actual interface name ovs-vsctl add-port br-dmz eth-dmz # Bring up interfaces ip link set eth-dmz up ip link set br-dmz up Alternative without OVS (using standard Linux bridge): # Create bridge ip link add br-dmz type bridge # Add physical interface ip link set eth-dmz master br-dmz # Bring up ip link set eth-dmz up ip link set br-dmz up Step 7: Assign Public IPs to the DMZ Bridge The bridge interface becomes your gateway for the public IP block: # Assign the first usable IP as the gateway # For a /28 block, .176 is network, .177 is first usable, .191 is broadcast ip addr add YOUR_GATEWAY_IP/28 dev br-dmz ip addr add YOUR_IPV6_GATEWAY/64 dev br-dmz # Example: ip addr add 203.0.113.177/28 dev br-dmz ip addr add 2001:db8:abcd:1e0::1/64 dev br-dmz Important: Set the MTU to match your WireGuard tunnel: ip link set br-dmz mtu 1420 Step 8: Configure Policy Routing This is the magic that makes it work. Traffic FROM your public IPs must route through the tunnel, not your regular ISP. Verify Policy Routing Rules The WireGuard PostUp commands should have created these: ip rule show Expected output: 0: from all lookup local 5: from 203.0.113.176/28 lookup 100 <-- Your IPv4 block 10: from all lookup main ... ip -6 rule show Expected: 0: from all lookup local 5: from 2001:db8:abcd:1e0::/60 lookup 100 <-- Your IPv6 block ... Add Local Routes to Table 100 Traffic within your public block should stay local, not go through the tunnel: # Local DMZ network (so hosts can talk to each other) ip route add YOUR_IPV4_BLOCK/28 dev br-dmz table 100 ip -6 route add YOUR_IPV6_BLOCK/64 dev br-dmz table 100 # Tunnel point-to-point network ip route add YOUR_TUNNEL_SUBNET/31 dev wg-coretransit table 100 # Example: ip route add 203.0.113.176/28 dev br-dmz table 100 ip route add 203.0.113.252/31 dev wg-coretransit table 100 ip -6 route add 2001:db8:abcd:1e0::/64 dev br-dmz table 100 Verify Routing Table 100 ip route show table 100 Expected: default dev wg-coretransit scope link <-- All other traffic via tunnel 203.0.113.176/28 dev br-dmz scope link <-- Local DMZ stays local 203.0.113.252/31 dev wg-coretransit scope link <-- Tunnel network What this does: When a packet has a source IP in your public block (203.0.113.176/28), the kernel consults table 100 instead of the main routing table. Table 100 sends everything through the WireGuard tunnel, except local DMZ traffic. Step 9: Test Public IP Routing This is the moment of truth: # Test outbound - does traffic from your public IP reach the internet? ping -I YOUR_GATEWAY_IP 8.8.8.8 ping -I 203.0.113.177 8.8.8.8 # Test IPv6 ping6 -I YOUR_IPV6_GATEWAY 2001:4860:4860::8888 ping6 -I 2001:db8:abcd:1e0::1 2001:4860:4860::8888 # Verify your public IP is what you expect curl -4 --interface YOUR_GATEWAY_IP ifconfig.me curl -4 --interface 203.0.113.177 ifconfig.me # Should return: 203.0.113.177 (or similar from your block) If this works, congratulations! Your public IPs are routing through Core Transit. Step 10: The MTU Problem (Critical!) Symptoms of MTU Issues After initial setup, you might experience: Pings work, but web pages hang or load very slowly SSH connects but freezes when displaying large output Small transfers work, large transfers stall HTTPS sites fail while HTTP works The Cause WireGuard adds ~60 bytes of overhead to each packet. If your underlying path has a reduced MTU (common with CG-NAT, PPPoE, mobile networks), large packets get silently dropped. Diagnose the MTU Find the maximum working packet size: # Start with a reasonable size and decrease until it works # The -M do flag prevents fragmentation ping -c 1 -M do -s 1400 YOUR_CORETRANSIT_TUNNEL_PEER_IP # Probably fails ping -c 1 -M do -s 1350 YOUR_CORETRANSIT_TUNNEL_PEER_IP # Maybe works ping -c 1 -M do -s 1300 YOUR_CORETRANSIT_TUNNEL_PEER_IP # Should work Example diagnosis session: $ ping -c 1 -M do -s 1400 203.0.113.252 PING 203.0.113.252 (203.0.113.252) 1400(1428) bytes of data. --- 203.0.113.252 ping statistics --- 1 packets transmitted, 0 received, 100% packet loss # <-- TOO BIG $ ping -c 1 -M do -s 1300 203.0.113.252 PING 203.0.113.252 (203.0.113.252) 1300(1328) bytes of data. 1328 bytes from 203.0.113.252: icmp_seq=1 ttl=64 time=25.3 ms # <-- WORKS Calculate Correct MTU The WireGuard MTU should be: WG_MTU = Maximum_Working_Payload + 28 - 60 Where: Maximum_Working_Payload = largest -s value that works +28 = IP header (20) + ICMP header (8) that ping adds -60 = WireGuard overhead Example: If -s 1300 works: Working packet = 1300 + 28 = 1328 bytes WireGuard MTU = 1328 – 60 = 1268 → round to 1280 (safe) or 1320 (aggressive) Apply MTU Fix Edit your WireGuard config: nano /etc/wireguard/wg-coretransit.conf Change: MTU = 1420 To: MTU = 1320 Restart the tunnel: wg-quick down wg-coretransit wg-quick up wg-coretransit Also update the DMZ bridge MTU: ip link set br-dmz mtu 1320 Add MSS Clamping (Belt and Suspenders) To prevent MTU issues with TCP, clamp the MSS (Maximum Segment Size): # Using nftables nft add table inet mangle nft add chain inet mangle FORWARD '{ type filter hook forward priority -150; policy accept; }' nft add rule inet mangle FORWARD oifname "wg-coretransit" tcp flags syn tcp option maxseg size set 1280 nft add rule inet mangle FORWARD iifname "wg-coretransit" tcp flags syn tcp option maxseg size set 1280 What this does: Forces TCP connections through the tunnel to negotiate a smaller maximum segment size, preventing fragmentation issues. Step 11: Configure Firewall Your gateway is now reachable from the public internet. Lock it down. Basic nftables Rules # Block inbound connections from the tunnel to your gateway nft add rule inet filter input iifname "wg-coretransit" ct state new drop # Block inbound connections from DMZ to your gateway (except DHCP/DNS) nft add rule inet filter input iifname "br-dmz" udp dport { 67, 68 } accept nft add rule inet filter input iifname "br-dmz" udp dport 53 accept nft add rule inet filter input iifname "br-dmz" icmp type echo-request accept nft add rule inet filter input iifname "br-dmz" ct state new drop # Prevent DMZ from reaching your private LAN nft add rule inet filter forward iifname "br-dmz" oifname "eth-lan" drop nft add rule inet filter forward iifname "wg-coretransit" oifname "eth-lan" drop What this does: Blocks the public internet from accessing services on your gateway Allows DHCP and DNS from DMZ hosts Prevents DMZ hosts from accessing your private LAN Step 12: DHCP Server for DMZ (Optional) If you want to dynamically assign public IPs to DMZ hosts: # Install dnsmasq apt install dnsmasq # Create config nano /etc/dnsmasq.d/br-dmz.conf Content: # DMZ DHCP Configuration interface=br-dmz bind-dynamic # DHCP range - only offer a few IPs from your block # Reserve most for static assignment dhcp-range=YOUR_DHCP_START,YOUR_DHCP_END,255.255.255.240,12h # Gateway (your br-dmz IP) dhcp-option=br-dmz,3,YOUR_GATEWAY_IP # DNS servers dhcp-option=br-dmz,6,1.1.1.1,8.8.8.8 # Example: # dhcp-range=203.0.113.189,203.0.113.190,255.255.255.240,12h # dhcp-option=br-dmz,3,203.0.113.177 Restart dnsmasq: systemctl restart dnsmasq Step 13: Make It Persistent (Survive Reboots) Create Startup Script nano /usr/local/bin/coretransit-startup.sh Content: #!/bin/bash # Core Transit Startup Script set -e echo "Starting Core Transit configuration..." # 1. Enable IP forwarding sysctl -w net.ipv4.ip_forward=1 sysctl -w net.ipv6.conf.all.forwarding=1 # 2. Ensure DMZ bridge exists if ! ip link show br-dmz &>/dev/null; then # For OVS: ovs-vsctl add-br br-dmz ovs-vsctl add-port br-dmz eth-dmz # Or for standard bridge: # ip link add br-dmz type bridge # ip link set eth-dmz master br-dmz fi # 3. Bring up interfaces ip link set eth-dmz up ip link set br-dmz up # 4. Assign IPs to DMZ bridge ip addr add YOUR_GATEWAY_IP/28 dev br-dmz 2>/dev/null || true ip addr add YOUR_IPV6_GATEWAY/64 dev br-dmz 2>/dev/null || true # 5. Start WireGuard tunnel if ! ip link show wg-coretransit &>/dev/null; then wg-quick up wg-coretransit fi # 6.

Verify tunnel if ping -c 1 -W 5 YOUR_CORETRANSIT_TUNNEL_PEER_IP > /dev/null 2>&1; then echo "SUCCESS: Core Transit tunnel is UP" else echo "WARNING: Tunnel may not be established yet" fi echo "Core Transit startup complete!" Make it executable: chmod +x /usr/local/bin/coretransit-startup.sh Create Systemd Service nano /etc/systemd/system/coretransit.service Content: [Unit] Description=Core Transit WireGuard IP Transit After=network-online.target Wants=network-online.target [Service] Type=oneshot RemainAfterExit=yes ExecStart=/usr/local/bin/coretransit-startup.sh [Install] WantedBy=multi-user.target Enable the service: systemctl daemon-reload systemctl enable coretransit.service Step 14: Verification Checklist Run through these tests to confirm everything works: # 1.

See Step 10. Works Initially, Breaks After Time Symptoms: Everything works, then stops after minutes/hours Common causes: DHCP on management interface adding rogue default route NAT timeout on ISP (increase PersistentKeepalive) Fix for rogue routes: # Create a cron job to remove bad routes crontab -e # Add: * * * * * ip route del default via YOUR_LAN_GATEWAY dev eth-lan 2>/dev/null || true Final Network Diagram After setup, your traffic flows look like this: DMZ Host (203.0.113.178) │ │ Packet: src=203.0.113.178 dst=8.8.8.8 │ ▼ ┌─────────┐ │ br-dmz │ Gateway receives packet └────┬────┘ │ │ Policy routing: "src 203.0.113.0/28 → table 100" │ Table 100: "default → wg-coretransit" │ ▼ ┌──────────────┐ │wg-coretransit│ WireGuard encrypts packet └──────┬───────┘ │ │ Encrypted WG packet: src=YOUR_WAN_IP dst=CORETRANSIT_ENDPOINT │ ▼ ┌─────────┐ │ eth-wan │ Sent via normal ISP default route └────┬────┘ │ ▼ ISP (CG-NAT) │ ▼ INTERNET │ ▼ CORE TRANSIT │ │ Decrypts, routes to internet as 203.0.113.178 │ ▼ 8.8.8.8 Conclusion That’s it! You now have real, routable public IP addresses at home, tunneled through Core Transit’s WireGuard service. Your servers can: Accept inbound connections from the internet Host websites, game servers, mail servers, etc. Use static public IPs that you control Work through any NAT, including CG-NAT The key pieces are: WireGuard tunnel for encrypted transport Policy routing to direct public IP traffic through the tunnel Proper MTU to avoid packet fragmentation issues Firewall to protect your gateway Core Transit has been rock solid for me. The tunnel reconnects automatically, speeds are good, and having real public IPs again feels like getting my internet freedom back.
