My goal is to connect to my LAN (10.11.12.xxx) from the WAN using Wireguard (same goal as this unsuccessful attempt). I had this working a year ago, recently nuked my router, and I can't get it working again. I can confirm that my client is making the handshake and transferring some data to the server, but I'm not able to ping the router nor any of the machines on the LAN.
SERVER config interface 'wg0' option proto 'wireguard' option listen_port '123' list addresses '10.11.12.1/24' option private_key 'REDACTED' config wireguard_wg0 option persistent_keepalive '25' option route_allowed_ips '1' option public_key 'REDACTED' list allowed_ips '10.11.12.210/32' CLIENT [Interface] PrivateKey = REDACTED ListenPort = 25812 Address = 10.11.12.210/24 [Peer] PublicKey = REDACTED AllowedIPs = 10.11.12.1/24 Endpoint = redacted.com:123 PersistentKeepalive = 25
It's probably a firewall problem, but I just can't figure it out. I added the wireguard interface to the LAN group, and I restricted to IPV4, because I had a vague memory of that fixing a problem in the past...
There are so many great tutorials about how to set something like this up, but not as much about how to methodically debug when it has gone wrong. Any hints?
