    Hi., i'm behind a WRT54GL runnin Tomato 1.22 Viktek's mod.

    My WAN connection is also my uni's LAN which has filesharing. i was wondering if it was possible to configure tomato to enable access of the shared resources of the LAN behind the WAN. i've tried DMZ, but deosn't seem to be working.

    my WAN's subnetted @ 10.X.X.X
    my LAN's subnet is 192.168.X.X

    thanks !

    DMZ is used if you want computers on the uni LAN to access machines behind your router. Is that what you want? I thought you wanted the opposite - to access machines on the uni LAN?

    Routers block most file sharing stuff but accessing by IP address should still work.

    quite correct, i need the exact opposite. was wondering if that was possible. any ideas? individual IP address accessing also doesn't work.

    You need to speak to the systems admin guy at the university about access.

    Sure it's possible if you have permission to access the shares.

    no no wait, i think i'm being misunderstood. our network is as such. we connect to the net via pppoe thru a LAN that has a gateway denoted as . the rest of the PCs are 10.10.0-2.X . my router is hooked up and my network behind the router is using a different subnet. i'm trying to access the PCs behind the WAN/LAN that are usually accessible if the PC is hooked directly onto the LAN with a 10.10.0-2.X ip address. but when they are behind the router, nothing on the WAN seems to be accessible.

    I don't see anywhere I misunderstood you.

    File sharing does not work as good across routers. But I know it does work by IP, I've done it.

    You will not be able to browse the network to find machines with Windows shares (you haven't clarified what type of file sharing to which you are referring, so I'm assuming based on your description) across distinct subnets. As mentioned, though, if you know the IP address of the other machines (or the full DNS name) file sharing should work just fine.

    Hi. well its just standard file sharing through windows between intranet'd computers on a LAN. as i've mentioned when i'm behind the router, i'm unable to ping those computers on the WAN let alone connect to them to access shared files. you mentioned that i should be able to connect to them assuming i know their IP address. doesn't seem to be working unless i'm doing something wrong.

    as i've mentioned, we're on 2 totally different subnets. how should the router or network behind the router be configured so that the resources on the WAN ie. shared files, LAN gaming etc are visible to those behind the router and vice versa is possible. i've actually tried portforwarding for multiplayer gaming, but it doesn't seem to be working. Thanks ~

    You should get ping working first.

    Restore the router to default settings, then try to ping a client on the WAN that you know accepts pings (that is, not being blocked by a firewall).

    It is entirely possible that Windows firewall is blocking you just because you are on another network.

    if you want other machines on the WAN side to be able to access your LAN machines maybe you could consider running a VPN server on your router.
