A standard Realm Host V2 tunnel connects a client to a server via a single endpoint. This creates a SPOF (Single Point of Failure) . If the server reboots, the network route changes, or the ISP experiences a peering issue, the tunnel collapses.

High Availability (HA) solves this by deploying:

When you combine Realm Host V2 with HA logic, you get the Realm Host V2 HA Tunnel—a resilient logical link that abstracts away underlying network instability.

To achieve HA, the configuration file (config.toml) would look similar to this:

[log]
level = "warn"

While "v2" can refer to a specific wrapper script (often found in repositories like realm-v2 on GitHub), it generally implies the usage of the second major iteration of the tool or configuration standards. Key characteristics of modern Realm implementations include:


Realm Host V2 HA Tunnel is an active-standby or active-active tunneling mechanism designed to ensure continuous connectivity between two network realms (e.g., cloud regions, data centers, or edge sites) even in the event of link failure, node failure, or network degradation. It builds on the original Realm Host tunneling protocol by adding redundancy, failover automation, and session persistence.




| Symptom | Likely Cause | Fix |
|---------|--------------|-----|
| Failover takes >15 seconds | Health check interval too long | Reduce interval to "500ms" |
| TCP connections drop every time | No connection draining | Enable [tunnels.drain] with wait_connections = true |
| Split-brain (both nodes active) | Firewall blocking VRRP packets | Allow protocol 112 (VRRP) between nodes |
| etcd timeouts under load | Low disk I/O on etcd nodes | Use SSD-backed storage for etcd |
