You may want to consider secure tunnels like wireguard or zerotier. `rathole` primarily focuses on NAT traversal by forwarding, which doesn't require any setup for visitors. + +- *Caching `local_ip`'s DNS records* + + As responded in [issue #183](https://github.com/rapiz1/rathole/issues/183), `local_ip` cache is not feasible because we have no reliable way to detect ip change. Handle DNS TTL and so on should be done with a DNS server, not a client. Caching ip is generally dangerous for clients. If you care about the `local_ip` query you can set up a local DNS server and enable caching. Then the local lookup should be trivial. |
