Hi! You need to read this: http://lartc.org/howto/lartc.rpdb.multiple-links.html ;-) Also, AFAIK, `ifupdown` doesn't handle multi-gateways, with load balance and etc, so, you'll need to configure it using "up ip ...", or, via /etc/rc.local (i.e., don't use "gateway" entry on /etc/network/interfaces on this case). I have a similar setup working here (multi-wan), I can share the confs if you want. Best! Thiago -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
