2801 ethernet expansion card for uplink to Internet

Question:

FA 0/0 - Internal LAN Cisco Switches Price connection

FA0/1 - WAN connection

We would like to use an expansion card that we have to give us an extra FA port to connect directly to the internet and use this router as our DMZ as well.

Would there be an issue using this expansion card for this purpose?  Can anyone give me an idea of the cpu load that this may cause?  Is this even possible?  At the moment we have a second router that is connected and is acting as our DMZ but we would like to remove this router and utilise the one router for all services.

Answer:

HWIC-1FE is a routable interface port while the HWIC-4ESW is a Layer 2 switch port.  As long as you have enough Catalyst Switches Price spare HWIC port, HWIC-1FE should work.
