I don't know if this is the best newsgroup for this question, but here goes: I want to set up my router to block certain services during certain hours of the day.
To select the services to block, I can create entries with port numbers, or a range of port numbers for blocking. In searching around, it appears that MSN Messenger uses ports 6891 to 6901, but I still find that it functions properly when the router should be blocking it.
Are there other ports uses by MSNM?
