I need PPPOE (I have Earthlink DSL). I have the router(WRT54GS) in PPPOE mode as per Linksys' web site instructions. My questions are in regards to my modem (Zyxel 645 series). In the modem setup: 1. Do I enable DHCP server, or disable it? 2. Do I hardcode the DNS server IPs Earthlink gave me, or leave them as 0.0.0.0? 3. Should I change the modem's IP address since it is 192.168.1.1 just like the router (i.e. will both of them having the same IP cause problems)? The modem's already in bridge mode, and I connect to the net fine when it's just the modem and my pc (using XP's PPPOE). But I have problems when I add the router to the equation. I have it like this: Modem -> Router -> PC. Thanks for any help.
