it looks like you might have a problem with your marking with the FW.

>-A OUTPUT -p tcp -m tcp --dport 80 -j others
>-A personal -j MARK --set-mark 40
>-A others -j MARK --set-mark 20

>From Looking at this I see the first commented link that as the mark in hex, Don't
all the marks need to be written this way?  0x80 0x40 0x20 ?

This is just a guess I don't really know.
