You must be _very_ careful when dealing with "iptables" and "ip" for
marking packets and routing them based on those marks. The numeric
argument to:
iptables -t mangle -A PREROUTING --jump MARK --set-mark 13
is a decimal number, BUT the argument to "ip" is an hexadecimal number,
so to insert a matching "ip rule" you should do:
ip rule add fwmark D pref 10000 table whatever
NOT
ip rule add fwmark 13 pref 10000 table whatever
Hope it helps.
