I want to set up a VPN using a Watchguard X5 to my office Watchguard over an AT&T DSL service.
I have a Speedstream 5200 modem w/ a single ethernet connector and single USB connector. Using ethernet to Watchguard WAN.
Watchguard has DSL service Username/PW info.
Since I cannot have the Speedstrem perform NAT, as the Watchgurad will, which Bridge Mode do I use in the Speedstream. Options are: RFC-2684 Bridged, RFC-2684 Bridged/IP, RFC-2684 Routed, PPPoE Client, or, PPPoE Bridged Mode, or PPPoE 2684 Bridged Mode, or, PPPoE 2684 Bridged Mode/IP
