Tomato Firewall Question

    Hello, I have two WRT54GL routers with tomato 1.19 set up for WDS to expand my network in my house. It seems to work mostly, but I'm running into two problems. First, whenever I use torrents, I seem to be having NAT problems. Is there some way to turn the firewall off completely on the second router? Or should I be port forwarding router #2 the same way I forward the main router? Secondly, while my windows box shows full signal strength now, my linux box is still only showing one or two bars. I'm not sure if this is the right place to ask about this, but I figured that I might as well incase someone has a quick fix for it. I'm using xbuntu 8.04. Any help of info would be awesome. Thanks! I followed the faq on the Tomato site, and set them up like this:

    First Router: 00:00:00:00:00:01
    The WAN port of this router is connected to the Internet.
    WAN
    (configure normally)

    LAN
    IP Address = 192.168.1.1
    DHCP Server = enabled

    Wireless
    Wireless Mode = Access Point + WDS
    SSID = myssid
    Channel = 1
    Security = WPA Personal
    Encryption = AES
    Shared Key = keykeyk3y
    WDS = Link With
    MAC Address = 00:00:00:00:00:02 (the *wireless* MAC of the 2nd router)

    #2 - 00:00:00:00:00:02
    The WAN port of this router is not used.
    WAN
    Type = Disabled

    LAN
    IP Address = 192.168.1.2
    Default Gateway = 192.168.1.1 (the 1st router's IP address)
    Static DNS = 192.168.1.1 (the 1st router's IP address or any DNS server)
    DHCP Server = Disabled (the 1st router handles it)

    Wireless
    Wireless Mode = Access Point + WDS
    SSID = myssid
    Channel = 1
    Security = WPA Personal
    Encryption = AES
    Shared Key = keykeyk3y
    WDS = Link With
    MAC Address = 00:00:00:00:00:01

    You cannot turn iptables off on Tomato, but you can make the conntrack timeouts very small, which might help for the conntrack/NAT problem.

    Don't go trusting no bars indicating wireless strength. Bars reflect whatever the author of the bar-showing-thing felt, so Ubuntu's 2 bars might be equivalent to Windows's 5 bars.

    Further, signal strength as seen by one Wireless card could differ vastely from what is seen by another wireless card. The 2 cards might have different receive sensitivities, and different antennas, making the "effective signal" to one card completely different to another card even though the 2 cards are sitting next to one another. Swap the cards around and test if that's the case.

    If you have 2 identical cards in Win and Ubuntu, we start looking at location - Is the one machine/card not experiencing wireless interference or obstacles (walls, fridges, cables, metal, plants, fish tanks, the computer case the card is in, etc.) that the other one is not.

    Another possibility is that your Ubuntu card is looking at the far AP. Under Linux you can easily lock a card to specific AP (by MAC address), while with Win it's difficult (if possible at all). Check the AP that Ubuntu is connecting to.

    Forgot to mention: Your WDS setup looks just spanky - no problems I can see there.
