We have a internet based 2600 router that I think is being access from offsite. I am wondering what the commands are to keep this from happening. I want to be only able to access the router from the console port. Is this just a simple no telent command? Or is there more to it. Also the router keeps rebooting itself and going to rom mode is this a memory malfunction? hacker? something else? Any help is much appericated.
