I have recently purchased a Cisco 871 router. In the GUI from the installed software, I have been able to configure which ports are forwarded to a specified IP address within my local area network.
This seems to output a configuration line like this:
ip nat inside source static tcp 192.168.1.123 1000 interface Dialer0 1000
However, I can only do this one port at a time. Is there a function or command that I can use to specify a range of ports? For example, I would like to forward tcp ports 1000-2300 to the IP address 192.168.1.123.
Any help would be appreciated.
