I have a network of 4 computers at home, using 192.168.2.x. On one laptop, I have Comodo 3.0.16.295, and although I thought I set the rules correctly, I can't share folders on the laptop with the other PCs. (The laptop can see and get files from the other PCs, and can be seen on the network and responds to pings.)
I tried accessing the shared folder from one of the PCs and then checked the Comodo firewall log on the laptop. It showed that it had blocked attempts to connect to Port 139, but strangely the attempts came from 192.168.44.1 and 192.168.206.1, not the IP address of the other PC, which is in the form 192.168.2.x. I've tried this a few times, and every time I try to access the laptop files from another PC I see similar log entries (accessing Port 139 from 192.168.xxx.1).
Then I tried pinging one of these funny IP addresses and I got this:
=============================================
C:\Documents and Settings\User>ping 192.168.206.1

Ping statistics for 192.168.206.1:
Packets: Sent = 4, Received = 2, Lost = 2 (50% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms
=============================================
I blanked out the last parts of the IP address that responded, but I checked it out via WHOIS and it's a legitimate one, owned by one of the ISP providers in my country.
Any idea what's going on here? Why am I getting access attempts from "private" IP addresses that are not on my network whenever I attempt to access the laptop from another PC and why does pinging one of these addresses get a reply from another (and external) IP address? (The wireless adapter on my laptop is turned off and I'm not running any wireless router.)
