blocking incoming udp packets

Hello Group:My system: Desktop and laptop networked through Linksys wired router.Question: My software firewall (Deerfield Visnetic) is constantlylogging blocks of incoming udp packets, the source being 192.168.1.1(which is presume is the router), destination being 255.255.255.255 or192.168.1.255.This doesn't seem to interfere with anything, but just watching theconstant bombardment in the logging screen is annoying.Can anyone explain what is going on here? Or what, if anything, I canor should do about it?I can set the firewall to block and stop logging all udp packets whichdo not have a specific rule. This eliminates the constant screenfilling. But I'm not sure if I should do this. I really don'tunderstand what is happening, which is why I'm asking for help.I guess I'm just concerned that my system may not be tweaked properlyand could be wasting resources. Perhaps I should change something inthe router setup via the web based configuration program.Here are a couple of the log entries, copied:2008/07/08, 05:32:18.406, GMT -0400, 2010, Device 3, Blocked incoming UDP packet (no matching rule), src=192.168.1.1, dst=255.255.255.255, sport=520, dport=5202008/07/08, 05:40:15.921, GMT -0400, 2010, Device 3, Blocked incoming UDP packet (no matching rule), src=192.168.1.1, dst=192.168.1.255, sport=8385, dport=162Thanks for any explanations, links to sites to educate me, orsuggestions.Jack

No problem! Enjoy. It's amazing what you can do with the quality third party open source firmware out there on the cheap. Especially look into OpenVPN functionality....
