I've got a 2621 that I am trying to do web caching with a CE507.
Both of my serial interfaces are connected to the Internet (same provider) and both of my ethernet interfaces are in use too.
Both serial interfaces are configured with ip wccp web-cache redirect out.
I've put the 507 off of e1.
The problem is that when I enable web cache on the router users that are off of e0 can't browse at all, while users off of e1 seem to be getting their pages cached just fine.
