Only route traffic for specific IPs into tunnel

Hello everybody,

I have two sites (site A and site B), both of them behind a Ipfire firewall with Openvpn configured. For specific clients at site A, I want to route all the traffic into the tunnel, so that when the client at site A accesses a webpage, it will use the public IP of site B.

Unfortunately, I can’t install a OpenVPN client, as the clients in question are SmartTVs. So, I thought about running a OpenVPN client on the Ipfire instance at site A, which redirects the traffic of those clients into the tunnel. Is that possible & has anyone done that already?

Any help is greatly appreciated!
