Hamachi Relayed Tunnel to Direct Tunnel Fix
Final Verdict
- 90% of relayed tunnels are fixed by enabling direct traffic + firewall rules + disabling IPv6.
- If still relayed, one side likely has CGNAT or symmetric NAT – no amount of port forwarding will fix that.
- In that case, switch to ZeroTier or Tailscale.
Run hamachi peer-ip [ClientID] to see the attempted route.
Step 2: Disable IPv6 (Surprisingly Effective)
Hamachi’s IPv6 relay detection is buggy on many networks. Forcing IPv4 often solves the problem.
Command Line Test (Admin):
- Solution: Use ZeroTier or Tailscale as a bridge, or simply replace Hamachi.
- Why this works: These tools use modern WireGuard or proprietary P2P stacks that handle Strict NAT and CGNAT much better than Hamachi’s aging engine.
