Specs: Cisco IOS
I have a router sits behind comcast modem. I want to setup the telnet access to this router from outside (public network) using the domain name. (the reason for domain name is because I only have dynamic ip address from ISP). Is it possible? Any IOS config example for this?

Note: I know how to setup the telnet access for the router. But does not know how to setup domain name and publish this name to public.

Does your router support Dynamic DNS updating? That seems like the easiest way.

If the router doesn't support ddns then you can still use it most likely. Might have to run an app on a local computer to send up IP to ddns service.

I did, and I don't have any complaints.

Configurations vary from router to router, and I don't have any Cisco router training. As always, Google is your friend.
