I'm trying to forward a port to an inside server. I have tried using static nat to forward it and I have opened it up in the access list as far as I know but I can't seem to get it to open.
The command is
for NATing the an entire IP, or
For specifc udp or tcp ports.
Then you need to have an access list on the outside interface that permits access to the port on the public address.
Also, make sure you have
The access-list bound to the external interface needs to include a rule to allow the incoming connection. Lets say you have port 80 is the port you want to forward. Lets also say that Dialer0 is your outside interface and FastEthernet0 is your inside, and 10.1.1.1 is the internal IP address:
Note that with this example, I have bound the NAT to the Dialer0 interface so that we don't need to hard code the IP address into the config - it will take whatever address the D0 interface has as the public address.
Also note that the permit command in the access-list allows access to any IP on port 80. Only use this method if the router does not route other addresses than the one used for the outside interface. Otherwise, hardcode
