Wireguard and NAT

[murmelbahn]

Hi all,

sorry for the general title of the topic but I'm not able to specify it.
My problem is as followed:

1x OPNsense Box
1x Openwrt Router

The Openwrt Router connects to the OPNsense box as a Wireguard client. At the Openwrt Router are more clients attached. I have disabled the masquarading for the Wireguard net on the openwrt router. I can access everything from one side to the other. But I have two problems with this setup:

1. The voip telefons / softphones on the Openwrt side does not work as intended. They ring and they connected to the sip registrar on the OPNsense side butwhen someone calls or they are called nobody hears the other.

2. There are a few road warrior clients on the same wireguard server. They can not ping or access anything in the openwrt side.

I think this is a NAT problem?

Maybe someone can point me in the right direction.

Can someone delete this? I had a typo in the ip address for the tunnels...
