2801 ethernet expansion card for uplink to Internet

[Angelo ANELLO]

Hi Guys,

     We have a requirement to add a connection to our existing 2801 router, running 12.4 IOS, to service an Internet connection.  Currently, the two built-in FA interfaces are being utilised for the following:

FA 0/0 - Internal LAN 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.

Any help/feedback is appreciated

Regards,

Hi Leo,

We currently have an HWIC-4ESW installed.  Will this work?

Thanks,

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