Need help Interpreting firewall logs

[Guest]

I need some advice on interpreting the firewall logs. 

What does this really tell me and what to interpret from the log...
On the second item i copied a very short list.  the actual log is much, much longer.  Is this typical?

First item, Summary log: 
Listed by source hosts:
 Dropped 25 packets on interface br0
   From 192.168.35.25 - 6 packets to key_udp(1947)
   From 192.168.35.36 - 1 packet to key_udp(138)
   From 192.168.35.72 - 1 packet to key_udp(138)
   From 192.168.35.73 - 3 packets to key_udp(137)


Second item, firewall log:
