Routing/NATing certain networks through VPN
«

Here's what I have done/got working so far:
1. connected to remove vpn server using openvpn
2. added a route for my wanted network to go through the vpn: route add 1.2.3.4/24 10.8.0.5
this works. I can ping the remote network from the OPNSense box
now I want to do the same with the clients sitting behind OPNSense
I setup an outbound NAT rule that says all traffic through the openvpn interface to be natted.
This *works* except it NATs ALL traffic, not just traffic for 1.2.3.4/24
Is there a way to do this without having to specify all my wanted networks in the NAT rules ?
I want only traffic through the OpenVPN interface to be natted

Did you put the outbound NAT rule on the OpenVPN interface?

Thank you, that was indeed the issue! I had done it on the the VPN name interface I created not just 'OpenVPN'. Once I changed the source, bam, it worked - you rock!
