Thanks for looking those up, dgkpcon.   Turns out it was a bit torrent client running on one of our machines and those were failed attempts to connect. That port was the randomly selected port in the client...  I had just installed it the other day when getting a linux distro and forgot about it while it was seeding.    Nothing like spinning my own wheels!   Jason        
I've recently started reviewing my networking logs from my router and I've found it's just buried with these entries, like thousands per hour.    I've done some searching and I can't find anything specific to port 61849. The good news is, my router seems to be doing it's job by blocking all these port requests, but I'm wondering if anyone has any idea of what it could be. The source IP's are all over the map.   Any suggestions on how to track down the source application(s) and/or stop these requests?
