I’ve recently set up WireGuard on a server using wg-easy (so the config files are generated, not typed out by hand) and I successfully connected a couple of peers, including another computer with an Arch-based distro. The last one to set up is my laptop with EndeavourOS and I just can’t figure out why this single device is not able to ping other peers (or reach http services hosted on those peers). Let’s say I’m trying to connect to a PC. The four most important bits (I think):
- The ping actually reaches the PC and the PC does respond (verified using tcpdump), but the response is never received by the laptop. I’m no expert but to me it suggests it’s not an issue with the wg config (
ip route get PC-IPreturns the correct interface).
- I disabled firewalld and it still didn’t work (tried looking at the logs before I did that but it also didn’t seem like it was blocking anything).
- The handshake with the server (where wg-easy is set up) works.
- I am able to ping the PC via it’s non-WireGuard IP.
I also tried some other common-sense solutions like restarting the interface with wg-quick, rebooting, switching to another network, nothing helps. I’ve no idea what could be the issue here, so any help would be appreciated
