Multiple static ips setup

    Hello, i'm afraid i'll have to seek a bit of help here because i'm having hard times trying to figure out some things.

    I bought a Linksys WRT54GS V2 router recently. I have a DSL internet line + a /29 ip block (x.x.x.121 to x.x.x.128). I have 3 computers behind the router, 2 wired and 1 wireless. Basically i want my routeur to have the .121 ip and want to assigned .122, .123, .124 and so on to any other machines i have.

    The way i did it so far is not quite good. I set a PPPoE with my username and pass, then i managed to set a ip (.121) for the local ip adress of the router (with a 255.255.255.248 mask). Then i went and configured the static ips to my 3 machines. Assigned the .122, .123, .124 ip adresses to my Local Are Connection cards, all with the 255.255.255.248 mask and the .121 gateway (router) ip. I have also put the .121 ip as a primary dns server for all my machines.

    Ok, after setting the user pass to my ppoe settings in the Linksys gui, i also set DHCP to disabled.

    Everything is cool so far, i have been able to connect to the internet and communicate between machines.

    Problem is to the outside world, all of my machines and router have been assigned one single dynamic ip.

    how can i set this so i can be showed with my static ips to the outside world?

    Thanks in advance.

    Tell me if i'm wrong, if i disable NAT on the router can achieve having my /29 ips showed to the outside world? Can i disable NAT on my Linksys router?

    NAT does hide your IP addresses. I would try it.

    I dunno if you can turn it off without custom firmware, and even then this would be really tricky, the linksys only supports 1 ip on the WAN interface by default...

    I suggested disabling NAT here because before i had this router i was using another dlink one. But back then, i was pluging my gnet modem into one of the LAN ports of that dlink router, the other computers plugged to the other LAN port. I remember in the modem configuration gui an unable/disable NAT button. When i was enabling NAT all my machines were having the same ip from the ourside world point of view. And when i switched to disable NAT all my machines were having their own static ips even to the outside world.

    So i suggested maybe if i can disable NAT or any other options into the linksys router i now have i could still have my machines showing to the outside world with their specific static ip addresses.

    But if what Guyfromhe say is true, then ouch.

    well if plugging them in to the LAN ports on the DLink worked than plugging it into the LAN port on the Linksys will do the same thing... i've never heard of a PPPOE conection that had multiple IPs before...
    if it's a non v5 of the WRT54G(s) line then you can put on custom firmware and join the WAN port in with the LAN ports so you don't loose a port....

    Updates!

    Switch the router to "router mode" instead of the default "gateway mode"and walla! All computers are showing their static ips to the outside world. How fun!
