I've a 1721 cisco router( with a 4port10/100 wic installed.

Is possible to filter using IOS firewall if wic address and lan address are similar? I know that is they have diferent ip addresses is possible, but if they are in the same LAN?

For example:

A server( connected directly to the router's wic FILTER and out using LAN interface.

Is possible?

best regards
