I know my way around the ERL fairly well, but I'm by no means a routing expert and especially not a VPN expert and I need some help setting up a layer 2 bridge where only one of the ERLs will have a public IP. See attached for a simple sketch of what I'm trying to do... Lets assume that the LAN I do not control doesn't use the 192.168.1.x IP space. Is what I want to do possible? Can anyone help me with how to set it up?
