I am setting up a hardware based VPN that will link 4 locations. I have 3 of them setup and working. In the fourth I have a Netopia 3000 providing DSL access. It uses PPoE to get a "sticky IP" (which as best as I can tell is a dynamic IP that doesn't change). I want to setup a Linksys VPN router BEFSX41 between the Netopia and my Lan. Right now the Netopia does DHCP. I am unsure if bridging mode is what I need to use or if there is something else. It seems to me that I need to connect a LAN port of the Netopia to the WAN port of the Linksys and then let the Linksys do DHCP.
Perhaps I need to pass through ports to the Linksys? If someone can tell me how to cable this and how to complete the setup I'd be very greatful.
