Hamachi Relay: Tunnel

The Hamachi relay tunnel is an automatic, transparent fallback mechanism that ensures connectivity when direct peer-to-peer VPN is impossible due to NAT or firewall restrictions. While it introduces higher latency and lower throughput, it preserves functionality for most remote access and small-team use cases. Users experiencing performance issues should first try to enable direct UDP hole punching; if that fails, accept relay mode as a stable, secure alternative.

This connection is fully encrypted and secure, but it acts as a middleman for the traffic. hamachi relay tunnel

| Metric | Direct Tunnel | Relay Tunnel | |--------|---------------|--------------| | Latency | Low (RTT ~10–50 ms typical) | Higher (+50–200 ms depending on relay location) | | Bandwidth | Limited only by client ISP | Shared relay bandwidth (may throttle under load) | | Reliability | Dependent on NAT/firewall | Very reliable (relay always reachable) | | Privacy | P2P (no third-party visibility) | Relay sees metadata (source/destination IPs, timing, volume) | | Cost | Free for up to 5 clients (relay still available) | Included in all plans | This connection is fully encrypted and secure, but
