I have a Netopia 4686XL that I manage through Telnet from a local workstation. I have found in the logs, then confirmed from an outside machine, that I can also log in through telnet from the outside. I want that to stop. But I cannot find the menu on where to block this option. I was thinking of just changing the port ot something else, but would rather not as I just want to change external ability to log in.
