What are these Firewall Events?

Hi,

i’m guessing they are nothing to be worried about but can somebody explain what my p.c is doing in these firewall events?

port 137 is a file sharing port
port 1900 is UPnP device probably a router at 192.168.1.1
Port 67 & 68 is DHCP
192.168.2.2 probably your IP address on the lan

Similar to what was stated below/ or above depending on your forum settings there is nothing to worry about 192.168.0.0 – 192.168.255.255
are private non routeable IP addresses and have to be on you lan
