Security Compromise? Port Fowarding?

Hello,

I've googled on this w/ no luck for hours. Perhaps someone here can help me.

I have a Motorola WR850GP Wireless/Wired router. When I look under the routing tab I have 8 different port fowards listed that I did not enter in.

There is more than one port forwarded, but they all only open exactly one port not a range of ports (I.E. Start 6881 - End 6881)

There are other ports also forwarded besides the above example, but none of them open more than one port per foward rule. Some are UDP and some are TCP forwards. I have more than one PC on my network. Aside from the above 6881, other ports forwarded are: 20545, 16441, 3074, 14594, 33016.

My question is: Since I did not enter these port fowarding rules, could the programs needing these ports fowarded have done it? OR do I have a security compromise?

I am using TKIP protection w/ a random 128 bit key... however wireless is always a security concern.

I know some file sharing programs ask for 6881 open, but could these programs have changed my ROUTERS configuration w/o a passkey to enter and change it?

Thanks for any Help!

Universal Plug and Play (UPNP) will do this if enabled.

What IP are they forwarded to? Then what machine on your network has that IP?
I believe 6881 is a music sharing service port.

 

What is UPnP?
UPnP technology extends Plug and Play to simplify the networking of intelligent devices in homes and businesses. When devices incorporating UPnP technology are physically connected to the network, they'll connect automatically to one another over the network, without the need for user configuration or centralized servers.

The UPnP specification is based on TCP/IP and Internet protocols that let devices communicate with each other. That's why it's called universal—UPnP technology doesn't rely on specific device drivers, using instead these standard protocols. UPnP devices can automatically configure network addressing, announce their presence on a network subnet, and permit the exchange of device and service descriptions. A Windows XP-based computer can act as a UPnP control point, discovering and controlling devices through a program interface.

This might not sound all that revolutionary when compared to regular old Plug and Play that's been around for some time. Adding Plug and Play technology to the operating system has made it easier to setup, configure, and add peripherals to a single computer. But the big deal about UPnP is what it can do for the home or small business user who isn't a networking professional, but who wants to be able to reliably play multi-player games, use real-time communications (Internet telephony, teleconferencing), and other technologies such as Remote Assistance in Windows XP. Until now, only big corporations with fully-staffed IT departments could do these things easily (though I doubt that multi-player gaming, much less a Web-surfing refrigerator, is a big part of their emphasis).
