We connect our branches with Cisco 1841 ISR routers by using VLANS on 4 port HWIC cards. It seems to me that we should be using the local ethernet ports on the router to route the WAN traffic and not the HWIC ports. If this is the case, are there expansion cards out there to give me extra local ethernet layer 3 ports?
We have multiple sites that have four WAN connections coming into the site. For example our wireless tower locations that are a hub for a number of locations. Currently we have four wireless connections hooked to a 4 Port HWIC card using VLANs. Is there a better way. I believe there is, but I don't know what it is.

interface we use the VLAN tag to demultiplex the VLANs. The switch needs
to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...
