First the short version: a program wants to contact another machine within a range I consider ‘trusted’, yet Comodo asks me for permission to connect to the Internet.
Now the long version 
Hi all, former ZoneAlarm user here. After ZoneAlarm turned into bloatware (slowing down my machine to such a level it was no longer acceptable) I had to look for something else. The Comodo firewall looks promising, but it does some weird things. Perhaps I do not understand the options well.
Here’s the problem I have. I have a home network, and I reserve the range 192.168.0.0 to 192.168.0.99 for my own (fixed ip) machines. This range I consider ‘trusted’.
In Comodo, I defined two zones:
- homenet100 - range 192.168.0.0 to 192.168.0.99 (my personal range)
- homenet255 - range 192.168.0.255 to 192.168.0.255 (broadcasting stuff, windows stuff, games)
(Yeah, I know, why not use the whole range, well, I use the range 192.168.0.100 to 192.168.0.254 for DHCP stuff, which basically means other people that I consider just as safe as the Internet :-))
In network monitor I added four rules:
- accept all traffic from homenet100 to homenet100
- accept all traffic from homenet255 to homenet255
- accept all traffic from homenet255 to homenet100
- accept all traffic from homenet100 to homenet255
From my understanding, this would create a ‘trusted’ network 192.168.0.0 to 192.168.0.99 plus 192.168.0.255.
Did I get it right thus far?
Now comes the interesting part… My laptop is running Synergy (a remote control tool), and when Synergy on my main machine tries to connect to that laptop, it is asking for permission to connect to the INTERNET, but lists an IP address within the trusted range (192.168.0.85).
What am I doing wrong?
