Hello.

I have a 2821 with 12.4T1 advanced security IOS and 4 adsl wics.

I cannot setup the router to work with this 4 adsl's simultaneously.

It works when i have the 2 of them up and running but when the 3rd comes up, the first(or second) from the first two fails ending to have 2 adsl's again.

Any ideas ? icon_rolleyes.gificon_rolleyes.gif

    Do you have any configs you can post to take a look at?

    solved, it has to do with dsl operation mode. Now i have 4 dsl in my cisco router.

    Ip cef is doing a load share in the lines, but i'm trying to find a better solution.

    The problem is that behind the router there is a firewall that NATs then internal lan. So if i decide to make policy routing i has to be done based on application, nbar i think can help me on this.

    any ideas ?

    One more think despite the fact that there is not a default route when one dsl from the 4 fails the router doesn't route the traffic through the other dsls and the internet stops.

    any ideas on this ?

    Thanx ;)
