Need to block ports for application.

I'm having a lot of trouble finding what ports an application uses. The application is called Voodo Chat, I want to block it for all of the wireless clients in my home (getting tired of them just sitting around on voodo and not doing anything done around the house ). I have a DGL-4500 router if that helps at all. Any help at all would be great.

Thanks

Yes I have read that, when I log into my router and look at the traffic for the wireless clients I dont see anyone using that port. I will try it and see what happens. Thanks

Can't you just remove the program from the computers.

You can also use the software WinNetStat:

WinNetstat

I don't think that will work for my problem, from what I understand that program has to be installed on the computer with vodoo, the computers that I want to put on a schedule when that program is blocked and allowed are not mine. But thanks tho

They are not my computers.

It's for incoming, not outgoing traffic. Let us know how that turns out.

Ok so I guess I'm kinda confused. I'm not sure how to set a schedule for when this program is allowed to run and when it is blocked. I have a DGL-4500 router.
