    Okay guys here it goes, I have the following setup:
    1 x Modem (w/router) ADSL
    1 x WRT54G running DD-WRT 23 (after two revivals :thumbup: )
    3 x Computers

    I want two computers of mine to be behind the wireless router, the other one must have its own PPPoE connection directly from the modem AND must be able to access one of the computers behind the router (which is my private mail server).

    So I have this:

    Pros: The computer can get the PPPoE connection directly because it's connected directly to the modem.

    Cons: That computer can't access the MX computer.

    Or this:

    Pros: That computer can access the MX one.

    Cons: It can't have its own PPPoE connection because somehow the PPPoE service from the modem doesn't go through the router. I've already used a solution from another user on this forum that allows me to now access the web management page of the modem but the PPPoE thing still doesn't work.

    Any ideas? :(

    Thanks in advance

    You have not explained why PC1 must have a PPPoE connection? Perhaps there is some other way to do, whatever it is that you are trying to do.

    Ok .. I didn't explain it because it isn't very correct the why I must have it, but here it goes. :grin:

    My dad and I play both an online game and even if we don't share accounts or anything there's still the risk that our accounts get caught if they show up with the same IP, this way, through different PPPoE connections we can have different IPs :)

    1. Go with the first option and setup a VPN so PC1 can access the MX. Possible simple VPN solution: hamachi

    2. Go with the first option and forward the necessary ports so that PC1 can access the MX. (Downside is that your MX would be visible to the internet... But if PC1 gets a mostly static PPPoE you could configure the firewall to only allow connections to MX from PC1.)

    3. Research the possibility of the WRT establishing 2 PPPoE connections and then do SNAT using setup from 2nd image.
