Routing Problem

[Gustafson, Tim]

Thomas,

No, I'm not using this box as a router.  It is a web server, and I need
to spread the load of my web traffic across two separate T1s.

I can't just add routes.  You need a default route, or parts of the
internet would become inaccessible.  In my case, you need TWO default
routes.  I have set up Cisco equipment and Windows workstations with two
default routes in the past, and it has worked.  In fact, I have one
Windows box right now that is configured on both these networks with two
default gateways, and it is working.

There has to be a way to make it work on FreeBSD.

Im confused.. if you have two T1s, then are using /30s dor the ranges?
If 
so.. what about not giving a default gateway for either one and just add

routes...

Are you attempting utilize this as just a router.?

Theres a section that covers setting up routing on interfaces in the 
handbook:

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-routin
g.html

Hope this helps
