Must be something about the nr traffic using the vpn tunnel setup by openvpn instead..
I've tried to only use openvpn for this today, running a vpn tunnel inside another openvpn tunnel and that is working perfectly.
Like this: Client1(with ip 10.5.5.2) is connected to a vpn server using a routed tunnel, client2(10.5.5.3) is connected to the same vpn server.
When both clients are connected to the server i connect the TAP(layer 2) openvpn between the two clients (inside the vpn tunnel). i know this causes a lot of overhead but this setup works. And i can access the whole network behind client2.

Hi esv,
The reason would be one VPN over another VPN, hence it causes too much overhead. Both OpenVPN and NR try to find the shortest route to send packets, when a VPN is ready before another, it definitely choose the VPN tunnel instead of the physical networks, if they are cross Internet or networks.
So it's not recommended run multiple VPNs, as it will slow down the performance fore sure.
