Hi ,

I have the following configuration on a cisco 2821 with two ADSLoISDN HWICs.

All HTTP traffic flows through Dialer0. All other traffic is routed through Dialer2.

What we want to do is, when connection through dialer0 is down to use Dialer2 for HTTP traffic.

Can anyone help?

Thanks in advanced.
