Modem -> Router (WRT54GS) -> PC Setup Question

    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
    3. Should I change the modem's IP address since it is 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.

    1. Enable it.
    2. Hardcode em.
    3. Change the router's IP to (or something like this). It is better if you leave the modem the way it is.

    Thanks, yHuKyM!

    Actually, and I did this last night before I saw your post, I ended up doing the exact opposite in each case:
    1. I disabled the modem's DHCP server (I'm using the router's)
    2. Because I disabled the modem's DHCP server, I had nowhere to hardcode the DNS IPs.
    3. I changed the modem's IP address, not the router.

    Everything works. But that being said, I think your advice would have worked just as well. In fact, I would rather have left the modem as it was, as you said, but it was too late and I already messed up the settings, and didn't know how it was set up to begin with.

    Thanks again.
