Help with Windows firewall log

Hi Experts:
I have this firewall log which I don't quite understand.
Could someone explain to me why there is so many dropped UDP connections from 0.0.0.0 to 255.255.255.255? My server IP address is 192.29.116.25
Also,why is this ip 192.29.116.22  try to connec to 192.168.116.255?

Thanks

Well actually you firewall is dropping DHCP requests

Requests are on UDP port 68, Server replies on UDP 67

When a computer boots up it has no ip so it uses 0.0.0.0 and asks ervyone 255.255.255.255 for help.

192.29.116.22 tries to send routing information to your subnet. You should check this, could be someone causing trouble...
