Problem with an ASA.

Answered Question
Jul 5th, 2008


I have an ASA and I'm trying to implement something like “load sharing” between 2 ISP's.

I tried to do “dual ISP”, but that's not what I intended to have…

I tried to implement “favoring static routes based on reachability”, but I did not succeed.

Somehow this last implementation is, I think, very near of what I need. The problem with this is that it has a limitation… it doesn't let me put 2 default routes pointing to 2 different interfaces (I mean, putting the traffic that leaves the ASA in 2 different interfaces), like this:


route outside 1 track 1

route dmz3 1 track 2


Can some one help me?

Thanks in advance,


I have this problem too.

ASA cannot do loadbalancing like a router.

You cannot have two active defalt routes. Only one will be active.

for redundancy you can use the following

  • 1
  • 2
  • 3
  • 4
  • 5

when you said "load balanced" you minted to say "load share", wasn't it so?
