doubt with a 4 port wic and 1721 cisco

[edgar-quintana]

Hi,

I've a 1721 cisco router with a 4 port wic.

This is my situation:

--the router uses one of those ports to connect to a ldms device.

--There are free 3 ports.

--The used port has a public ip address

Now, we need to connect a server to a free port and then go to internet using IOS firewall but asing a diferent public ip addres...

Is hard to explain.. hahaha

On the Cisco 1721 router, these cards can be used as trunk interfaces for data services only, such as fractional n x 64-Kbps service for WANs (Frame Relay or leased line).
