Good day IT Staffers! I'm interested in finding a piece of software that would allow me to give a user access to our gateway so they can access the internet for a specified period of time.

Example: User asks me for internet access to research something, so i need to manually configure their network settings, and hope i remember to go back and turn them off later.

What i would like is set up a program, pref with remote access, that i can specify a time interval (say 1 hour) that they have access to the gateway, then it locks it down again. Since this could be any number of users, at any given time, for a random amount of time, each instance would need to be custom, so a GP wouldnt work in this case. Has anyone seen anything like this? I'd really like something cheap/free that can do this... I dont have so many users that spending a thousand dollars on this sort of thing would be justified.
