Hi alzhao, I have been having a dialog with hansome here in [this thread](https://forum.gl-inet.com/t/wireguard-openvpn-connects-but-no-lan-access-when-running-in-repeater-mode/27497/15) but with no satsifactory outcome as yet. I would like to keep my set up simple. **Some questions on the above:** a. If I have a perfectly working iPhone WG config, does that mean that Scenario 1 is not my issue? Or it could still be? b. If so, then can you please provide an example of a port forward on the Server; and why do I need it if it works on the iPhone with an App but not on the GLiNET Device set up as a client? c. If you suspect UDP port is blocked (PCCW?), can you please give examples of these “extra settings” you refer to please; and again, why do I need it if it works on the iPhone with an App but not on the GLiNET Device set up as a client? k. --- _[View the full topic](https://forum.gl-inet.com/t/4-x-wireguard-rekey-timeout-troubleshooting/25814)._
