    I recently switched the firmware on my WRT54GL from DD-WRT to Tomato.
    I noticed that when I am running torrents, the router tends to lock up. I used to have this problem with DD-WRT but it could be remedied by changing the maximum number of connections and changing the timeouts.

    The problem is that the same settings in Tomato are more complicated. In DD-WRT I just needed to make changes to 3 values. In Tomato, I have 12 values to change.

    So I was wondering if anyone can provide stable values that will prevent my router from dying from torrents?

    I have max connections at 4096, just don't know what to set the other values to. When I drop idle connections, everything is much better.

    You can decrease UDP timeouts. It is fine since UDP is stateless meaning that jobs done if it reaches the other end so you can dispose of it.
    I think maxconn at 4096 is a little low.
    If the max connection setting cannot be modified via GUI you can do it by modifying systctl values.
    Login via SSH
    then
    sysctl -a | grep maxcon
    find the sysctl variable then
    Change it with sysctl -w.
