I have a Pi running PiVPN, which is now connected to a router running OpenWRT. Does anyone have a link for me where someone describes how I have to set up OpenWRT regarding port forwarding and Firewall-Settings for PiVPN/Wireguard?
I THINK I have the port forwarding figured out, but the firewall-settings confuse me. Do I even need to set up a traffic rule?
It was easy on my Fritzbox-Router, but I find OpenWRT to be a bit more complex with all the functions it offers.
If anyone stumbles accross this post, here is how I solved it for me:
PiVPN doesn’t need any special firewall-treatment in OpenWRT, just use port forwarding (Source zone: WAN, Destination: LAN, with the Port you chose, 51820 is the standard for wireguard)
A special problem I had: I used NordVPN on OpenWRT to tunnel all my traffic through there. When I connected the PiVPN, it didn’t work at first. I had to use something called PBR - Policy-Based-Routing to send all my traffic from the PiVPN to WAN. It was easy with the openWRT-app vpn-policy-routing plus luci-app-vpn-policy-routing
