Title: Wireguard connection working but no internet access
Post by: steilfirn_8000 on January 03, 2022, 08:17:09 PM
Hello there,
I recently enabled Wireguard for a "roadwarrior" setup.
In general it works out of the box and I can connect my Android phone with OPNsense.
Also pinging, DNS resolution and so on works flawless

BUT as soon as I open my Firefox browser and try to open a website it times out.
Any ideas why that happens?

Very difficult to troubleshoot when you give no information on the configuration. But I suspect you have set up AllowedIPs on your Android to 0.0.0.0/0 but haven't created an outbound NAT rule on OPNsense

See https://docs.opnsense.org/manual/how-tos/wireguard-client.html for help with setting it up properly

Hello Greelan,

sorry I did not mentioned earlier: I do have an outbound NAT rule on my WAN interface (was created automatically).

In general I have a /29 subnet for my android phone and my phone uses 0.0.0.0/0 to route any traffic via the wireguard tunnel.


Personal I think it might be an issue on the routing table of Android as after a while I am able to surf the internet.
