I'm struggling to set up a port forward in a cisco 2600 router.
My internet comes in through a wic-adsl card, it is configured with no ip address. My dialer0 config gets the ip address from my isp (eg aa.bb.ccc.ddd). My LAN connects to f0/0 which is set at 172.16.1.30. My PC is set at 172.16.1.15 and I need to forward a port number to this PC.
I tried 'ip nat inside source static tcp..etc in the dialer0 interface but I got
router(config-if)#ip nat inside source static tcp ....
% Invalid input detected at '^' marker.
I've seen 'ip nat inside source static ' in cisco documents but I don't understand why I'm getting an error when I do it.
Thanks for any pointers.
not apply the ip nat inside command in the interface configuration mode.
put the command in global router configuration
router# conf t
router(config)# ip nat inside source static 18.104.22.168 x.x.x.x
