Actually, I was able to determine it's source late last night..It turns out that P2P software Kazaa was causing the connections to come back, I can't imagine what it uses UDP 1815 for, however, as I blocked all incoming queries to that port and was still able to search and download files..while doing so I saw many packets attempt to come in on the suspect port, but all were dropped by my firewall. Like I said, not sure why this traffic was occuring, but at least I know what was causing it.. Thanks everyone for your answers.

It appears MMPFT is the acronym for "Multimedia Portables For Teachers". Not a heavily used service I would think. You say you these packets are coming to your home machine. Can we assume this is a dynamic IP connection and perhaps the packets are intended for the user assigned that IP from an earlier time? Unfortunately, UDP provides few clues and it is often hard to draw any conclusion unless full payload captures are available.

Subject: Traffic on UDP 1815

Hi all, longtime lurker, first time poster to this forum. I've been seeing a lot of traffic on my home Win2K pro machine lately from random IP's/high numbered source ports to UDP 1815, which is registered as "MMPFT"..this is all the information I can gather on it though..anybody have any insight into what this might be? I'm hoping someone's seen it before.. I also checked, there is no initial packets sent out from my machine to any of these source IP's..so I don't suspect any kind of callback, and I don't really expect any sort of intrusion at all..just curious as to what this service is..

Thanks in advance for any replies
