I have a situation where i am installing a wan aggregator(barracuda). I need to install the aggregator in front of the firewall, which is a c1811 router/firewall. The router/firewall will need to service two wan ip adresses from each isp because there is a seperate router terminating each isp. It looks like the only way i'm going to be able to do this is to define two ip addresses on the c1811 or ailiasing the external interface on the c1811. Is the c1811 capable of this? if so, what is the accepted method of doing this. Thanks
