Hello, I have this configuration working without any bridge. Openbsd rl0 <- LAN1 -> Router <- Internet -> RemoteFW <- LAN 2 -> SomeDevice My PC is connected to a LAN1 switch, and it's able to ssh SomeDevice. As you can see my OpenBSD has just one interface and the VPN is mounted between OpenBSD and RemoteFW.
