I dont have the firewall logs since i deleted them but I use ZA and I used Sam Spade to perform the 'traceroute' as well as 'whois' for each hop. In the subsequent 'whois' of the hops i found the computers of different countries. Also the number of hops were around 20 which made it a bit strange as usually they are around 2-5 for the same IP range.

right now I was scanned for netbios (5 times) by an IP from my subnet and the number of hops is 2
