I have a 1720 Modular access Router, a WIC-1ENET interface card, and a 24-port Dell PowerConnect switch. I have residential cable internet service with a dynamically assiged IP address. I would like to configure my router to allow basic internet connectivity as well as forward several ports to my web server to allow the hosting of a few services such as HTTP, FTP, and remote desktop. Basically, I would like to know if this configuration is even possible with my current service and equipment.
Any suggestions and/or feedback is greatly appriciated.
Re: 1720 Router, Dynamic WAN IP, and Port Forwarding
Thanks for the article...it's very detailed. I have used NAT on my older residential gateway (Netgear RT311). I may be misreading the article, but it seems as though a port on an internal IP address can only be "linked" to a IP address on the external interface. Since I have a dynamically assigned IP from my ISP, I would need to translate a port to the external interface itself rather than the IP address. Do you know if there is an IOS command that allows for this?
