I am not well versed with CISCO IOS and can get by with the basic.  Please be patience and be detailed with your help.

I would like to port forward 80, 443, 25 to different internal IP address for each  to flow from FE 0/0 to any of the ports in the LAN side and block other unused ports.  Can someone provide the command lines to do so?

Thanks in advance.

You need to configure an access-list and apply it to the interface inbound. This can be more complex depending on exactly what else traverses the link I.E DHCP requests.


interface fastEthernet0/0
ip access-group filter in

ip access-list extended filter
 permit ip host 0.0.0.0 any
permit tcp any host 10.1.1.0 eq 80
permit tcp any 10.8.21.0 0.0.0.255 eq 443
permit tcp any 10.8.21.0 0.0.0.255 eq 25
