HTTP and DNS behind NAT

Hi All

I have cisco 2621 router with IOS version of 12.1.

My office has Web/FTP server setup on private ip range. So i did NAT using

"ip nat inside source static tcp 192.168.1.11 21 xx.xx.xx.xx 21 extendable"

so i can access FTP from outside. I also wan my webserver setup from outside. I gave same command line for port number 80, 53 [TCP/UDP], as DNS is also maintained locally only....

Is there else config required to let HTTP work by domain name..

Thanks,

Dhaval Tandel

Dhaval,

You need to contact a DNS hosting company and have them host this internet domain name for you. They can create an 'A' host pointing to the public ip address you assigned to the router.

Your internal DNS won't help resolving this IP since the clients are coming from the outside.

You are done as far as Cisco config from the router side.
