One simple way to do this is to use two routers, one for each external interface. You can then select which circuit is used by pointing the default route on the client machines at the appropriate router. When using old PC hardware and FreeBSD, routers become pretty cheap. ;^) The other solution would be to NOT define a default route on the router, but rather to configure gated with both interfaces in Silent or Active mode, and let the learned routes take care of the problem for you. These would still be routed by destination, not by source, but the overall effect should be to balance the load according to the "costs" of the routes. This conversation is much more appropriate for the freebsd-net mailing list, so I've cc'ed it over there. Please rejoin the thread there, if necessary. -- Where am I, and what am I doing in this handbasket?
