[newjack]

I had a Question about the default setting in firewall.I have a single computer i am running.As of right now i am not using a printer or sharing connections with other computers in my house.Do i have to have Upnp checked as seen in image below?Not sure if it is used for other connections other then devices,printers,ect. Unless i understand this wrong. Image below.

Hi Newjack,

Plug and Play sounds like something to do with gaming, like I have my xbox 360 Plug and Play kit,

Although it does say Universal, So I'm not quite sure.

Thanks.

Yes i believe that is part of the function.But I do not use xbox or any plug in gaming.This is how it came as default.I don`t want it checked unless it is needed by something I dont know about.I think it is also used if you have more then 1 computer and for sharing.This is why i am trying to find out.Anyone else know?

If you've only got a single stand-alone PC at home, without any home network set up, then you probably don't need UPnP to be enabled unless you've got a Wi-Fi box. If you're not using a Wireless connection to the internet, I'd say you can uncheck that box.

Wikipedia has an article here - standard disclaimers apply about the accuracy of what you read on Wikipedia.

Of course, what I said earlier could be a load of dingo's kidneys. If you uncheck the box and suddenly you can't connect to the internet, then, well .... come back and tell me so. Better re-check the box first, in that case.

Actually a good question for those who know will ask...

It's typically used by My Home Network to detect other machines on the 
network.
Many home routers (Linksys etc.) use UPnP.  If he/she can 
confirm that theirs doesn't, and they don't have any networked home appliances, 
consumer electronics devices and wireless devices (more details here - http://en.wikipedia.org/wiki/Universal_Plug_and_Play), 
then I can't see a need for it in that environment.

This from our T3 tech. Same link as Peter's I see

Thanks very much to both of you guys.I did a little searching myself and thought it would be ok.But i was uncertain if there was another function related to this.After looking,it is associated with 3 ports 5000,2869 and 1900.Was unsure if any of the others were needed for some unknown reason.I did uncheck for now Hayton and still have connection.It seems to be working fine for now.Thanks again Hayton and peacekeeper.                                                                                        newjack
