But you can have the two lines to Internet each connected to different
ISPs, and each won't accept the other's packets, so having one of the two
routes is a lose - lose situation, as only one route could work at a time.
What you need it linux-2.2.x (or 2.0.x with patches) and
CONFIG_IP_MULTIPLE_TABLES turned on. Then you need tool ``iproute2''. Here
are some references (I got them from kind souls on [EMAIL PROTECTED]
list) :

Hope this helps,
Jan
PS : I'm probably gonna try to set this up this weekend ...
