appling access list that allows dynamic ip telnet connectivity.

I connect to a firewall via a VPN connection from home. I then telnet to a router in that same network and get denied because of the access list. If I do an ipconfig on my home pc I can see my IP address and then have someone at the NOC apply that IP address to the router access list as a permit. I can then VPN in and telnet to the router successfully. Because my IP address at home is never the same (Dynamic) I must change the access list each time I establish a new session. Is there some option on the router that I can set up to avoid this problem. Such as, have the routers access list look for authenication instead of IP.

Open the port 23 in the FW.

Then not any particular IP, but Telnet session from every "legitimate" IP will work.

Best,
