Port Question

[neutec]

Hello All,
I have asked this question before with no answer so Im hoping someone may know this time. I am using a Cisco 2514 router with IOS 12.2 ans a firewall set. Im currently just using nat with a simiply ACL rule set. everthing is working great but I would like to make all my ports on my router to be hidden and not just closed. If I run a port scaner on my router I can see all my closed ports. I would like to hide these ports if scanned. does anyone have any thoughts how to do this?

Thanks

Hmm, on an IOS Firewall ? i don't think so, maybe disabling outbound ICMP Port/Net Unreachable from the router, which is probably what the scanner is looking for to determine if the port is closed by an ACL. I am not sure if that will work, otherwise this functionality is found only in the PIX firewall (in cisco products that is)
