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

you can use two or more IP addresses per interface. Cisco calls it ip
address secondary.
