Hello,

Is there a way to route p2p traffic on a separate ISP connection, just as
you would choose a separate connection for http traffic?

I tried all sorts of setups based on:
http://www.braindump.dk/en/wiki/?wikipage=PolicyRouting but with no luck.

Please help :)

(ipp2p is up and running)
you should MARK your packets in PREROUTING -t mangle, then identify them in iproute2 with fwmark. It's simmilar to this:

table_syn=mytable
$IPT -t mangle -I PREROUTING -i $LAN \
-m multiport -p udp --dports $INET_LOWLAT_UDP_PORTS -j MARK \
--set-mark 1
$IPT -t nat -I POSTROUTING -s $LAN_NET -o $INET_LOWLAT -j MASQUERADE
ip rule del fwmark 1 lookup $table_syn &> /dev/null
ip rule add fwmark 1 lookup $table_syn
ip route del table $table_syn &> /dev/null
inet_lowlat_gw=192.168.22.22
ip route add default via $inet_lowlat_gw dev $INET_LOWLAT table \ $table_syn
