 Subject:  Port UDP 1574
 Date:  Mon, 22 Jan 2007 14:44:30 +0100
I'd like to post a part of my m0n0wall firewall log hoping someone can 
help me finding the reason why I have my log full of the same data and I 
don't know why.
I searched google to find something about 1574 udp port but found 
nothing except the fact it's mn-mlevel port.
What does it mean? What is the mn-mlevel port? I guess it can be 
concerned with my p2p programm because the source port is, most often 
than not, the same: 4672.
Those data is blocked by the firewall but I'd really like to know what 
kind of data that is.

The strange fact, I think, is that I natted the udp port I use (36838) 
for my emule and all the data that pass through that cause no problem.

I hope someone can help me.

! 87.17.69.98 is my WAN IP address.

Thanks a lot, Michele.
