Unexplained apps in Linksys port forwarding

I have a linksys wireless router - BEFW11S4 and I have a desktop and
laptop using wireless connections to the router. Everything works
I wanted to FTP to the desktop from outside my house so I loaded a FTP
server and because I was told it would be safer - I mapped a random
high port number ot port 21 . All this worked fine.
Recently I went back into the router and noticed that there were 2 new
apps in th port forwarding which I did not add! I can't find anything
about them. Or - I can't understand how they got there. I couldn't
find anything about potential security problems with the router except
vague references .
I disabled all of it
How can apps get added to port forwarding in the router? Is this a
hack or security thing? or is there a way for apps to update the
router. (I changed the admin password from the default) .
As far as the apps added - they are:
ELFP?Ð from Ext port - 1334 to Int. port 5292 using UDP
ELF??Ð from Ext port 2837 to Int port 5276 using UDP
I don't see any of the ports using netstat -a
Any ideas on how this happend or what these are?

your router and disable UPnP. The ports are probably owned by MSN Messenger and are random. If you're using MSN Messenger, then leave UPnP turned on as many of the features don't work unless it is enabled. There are also other programs that use UPnP to automagically configure holes in your firewall for their benifit.
You can also turn it off on the computah end. In Windows XP: Start -> Control Panel -> Add/Remove -> Add/Remove Windows Components. Scroll down to Networking Services, and uncheck "Universal Plug and Play".
