Hi @hansome
after setting the option “allow-recursive-routing” in the .ovpn file, it worked!! Thanks a lot for your help. I really appreciate the great support here. So now I only have to delete the wrong route like it was advised by you in this thread (Router as Wireguard client blocks LAN reachability to same Wireguard server the router is connected to - #18 by hansome) after starting the vpn client and then everything is working fine.
Hopefully this will get fixed in the next firmware.
Currently I’m using this cronjob to fix it automatically:
* * * * * (if IP=$(route | grep UGH | awk '{print $1}') && [ -n "$IP" ]; then ip route del "$IP"; fi) >/dev/null 2>&1
Cheers,
