I have no experience with the Ericsson. I have set up PPPoE DSL in bridge mode with the help of the ISP, but it required that I upgrade my service to a subnet from the ISP. I have done this with Cisco 675 and ActionTec modems, but not Ericsson. My modems then had their own IPs and "passed" the other external IPs to the routers. This allowed my Routers with hardware VPN to have an external IPs... but i digress. This configuration configuration works great if your ISP supports it, but I was assuming that you had control over the Ericsson and it was configurable to support multiple IPs for your LAN.
