hey i am running wireguard vpn (10.10.9.X) behind 2 routers 1 (isp crap 192.168.3.1) 2. pfsense (192.168.3.155)... i am trying to connect to it from inside the first router (192.168.3.X my pc address) pfsense router ip 192.168.3.115. how would i go about connecting no matter what endpoint ip i set i cann't connect to it from inside the first router tired default gateway of ISP (192.168.3.1) tried using pfsense ip (192.168.3.115) and i tried using public ip. works fine if i use mobile data but it's dumb to use mobile data at home since i don't have unlimited

Can you clarify how this is configured more clearly? You mentioned two different IP addresses for the pfSense router on the same subnet.

Also I assume you are port forwarding from the ISP router which is why the mobile data works?

What are you trying to achieve here?

I would expect you to be able to access the Wireguard network (10.10.9.x) when connected locally like this but any attempt to connect to something else on 192.168.3.x gets confusing as your PC already knows its connected directly to that LAN so wont use the Wireguard link, but Wireguard may also be trying to force all traffic over itself (if you specified AllowedIPs = 0.0.0.0/0), so all access to 192.168.3.x is likely blocked at that point.
