i just tried over an hour to bring a tunnel up on one of my other servers, so i can simulate routing behaviour with it, but just wasted my time with trying to fix a broken ppp installation on it. dont have the patience and gotten way too tired to do that right now. so i give you the configuration of my testing setup and if you would like to reproduce it i would appreciate it. iptables -t mangle -A PREROUTING -i eth4 -s 192.168.0.22 -j MARK --set-mark 0 ip route add 192.168.0.0/24 dev eth4 table test ip rule add fwmark 1 table test OR ip rule add from 192.168.0.22 table test (these ones done in the ppp ip-up script) ip route add <remote ip> dev <ppp iface> src <local ip> ip route add default via <remote ip> dev <ppp iface> (dont use a default route in the main table to the same ppp iface, so you feel a difference when the routing rules apply or not) thats all i think.
