This is a bit tricky question. I want some option through which I can block internet connection for sometime without turning on the lan. I have a small office where people launch download or stream media. This affect the backup process which is initiated through automated tool which works on lan and stores the data in NAT.
I need some way through which I can stop internet connectivity only at the time of backup process so that it can be completed faster. Is there a way to do the same.
