Re: multiple internet gateways



Thanks Walter,
I have an old 1720 with three enets, will that work? I was just
reading about policy based routing, are you familiar with that? So far
it sounds like just what I might need.

Can the ASA 5510 be somehow configured to use two internet gateways on

use one pipe and the rest the other since I have two independent T1's.
If not, how else can this be accomplished?

You would have to figure out how to do source-based routing. I
don't know how easy that would be; it couldn't be done in the
old PIX 5/6 series, and if I remember my reading correctly it
couldn't be done in PIX 7.0, but I have not followed up on the
7.1 or later features.

I believe what you would want in order to do this would be
multiple security contexts -- but security contexts are not
supported on the 5510.

What you -can- do on the ASA would be to NAT the different groups
into different source IP ranges as they exit the ASA. You must
have some kind of router "in front of" the ASA already in order to
handle the T1 interfaces; if you can do source-based routing on that
router than the problem would then be solved.
