I got my android device connected to my openwrt router with wireguard. I can browse internet and confirm that im using my public WAN at House #1. But the problem is i cannot access my pc at House #1 nor I can ping any devices. I want House #1 and House #2 can see each other's network so i can still access my server pc. I tried playing with firewall but no luck. Anyone here can help me? Thanks!
