bridging my ISP's router to mine without bridging?

    i just had my cable broadband upgraded to 100mbps and i got myself a linksys E3000 to take advantage of it, but my ISP doesn't do a modem only install and they only have a single router/modem combo box (a thomson twg870) that they are using and has no bridging option, but it's not a patch on a good router running tomato and is very light on features by comparison, so i've been trying to get everything connected in a way that makes the isp's router transparent and i'm a bit stuck.

    i've got a few port forwards etc. set up which were working with my old regular cable modem which used to give the WAN port on my router a public IP which was great, but obviously that doesn't seem to be possible now and pretty soon i'll want to be doing some online gaming on the psn, xbox live etc. and i can see this being an issue, not to mention the lack of access to my nas.

    so far i have the isp's router with everything turned off except dhcp (which i plan on turning off later when i'm home, but i don't want to lose my remote connection by doing it now from work:)) and set as 192.168.0.1 with my router connected to that with a WAN IP of 192.168.0.11 and my own internal LAN on 192.168.1.x with the tomato router as 192.168.1.1 and everything local to me using it for the DG, DHCP & DNS.

    my isp's router has a single DMZ host option which i figured would basically make their router transparent to incoming traffic and open up my tomato router to the internet, but that's not the case unfortunately.

    i have a nas connected to my router and dyndns set up so when i browse to my dyndns hostname + the correct port for my nas, i get to it's web interface, which has been working fine for years on my old linksys wrt54gs and my new e3000 before i got the new isp router, but i can't get it to work now.

    i tried setting up a blanket port forward on the isp's router from 1-65k pointing at the wan port of my tomato router on 192.168.0.11, but that hasn't worked either.

    does anyone have any ideas? :)

    setup DMZ on your cable/router to your E3000s WAN side IP "I would set this static like you mnetioned", then do a port forward rule on your E3000 to forward say 8080 or whatever HTTP port assigned to your NAS servers LAN IP.. should work.

    i was hoping to be able to set it up without having to duplicate every port forward on my isp's router as well as my own.

    i thought a blanket port forward would do it, but apparently not.

    oddly enough, it seems to have sorted itself out now and is working fine.

    not sure what the problem was initially, i thought maybe it took a while to update the routing tables or something, but i tried changing the WAN IP of my router and adding that as the DMZ host in the thompson and it's still working.

    ho hum, alls well that ends well i guess, but thanks for the help anyway. :)
