Hi All

Have a friend with AT&T dsl. Has a Motorola dsl modem model 2210 and a Linksys E1000 router. AT&T has the modem in bridge mode and the Linksys router using PPPoE with user name and password. What is the reason for setting it up that away? He uses both wired and wireless on the router. Three computers and one wireless printer. Cable from dsl does not go into WAN port on router.

Thanks for any info on this.

Hello Reddoug: Any particular reason for "Cable from DSL does not go into WAN port on router"? as this will basically defeat the purpose of router (NAT) and some other functionality

Hi

That is the way AT&T had him set it up is all I know. Trying to figure out why they would want it that way.

Thanks for the reply.

The main reason to bridge a modem is to eliminate IP address conflicts. Linksys uses a 192.168.1.1 and At&t modems use the same address. Bridging also eliminate NAT conflicts between two routers (dsl modems are routers without a switch). Gamers usually have issues with restricted NAT when using two devices. It's easier to port forward or use a DMZ through one device. Linksys routers are a lot easier to configure for networking than most ISP modems.
