Although I’m not really sure if it was adequate enough, I was satisfied with my router the Windows firewall. The main reason I installed CFP was because I was leery of hotspots.
Will I need any additional rules in addition to the global one for my private network?
I downloaded Comodo’s Trust Connect but really haven’t had time to investigate how it works.
The main thing to avoid is having a trusted network. If you connect to somebody elses 192.168.1.1 and there are other users there, you don’t want to have them see you or talk to you. So to set it up, don’t automatically recognize new networks and trust them, block traffic between the router and your NIC (add it back in if things stop working). Treat your router like it was in somebody elses house and you were secretly using it. As far as what else to do, use SSL/TLS email links (gmail if your ISP doesn’t support it). Don’t expose your user name and email password in the clear (problem with most NNTP servers, so skip Usenet). I sail throughout the area (spent 7 months in Mexico last Winter) and found that only a few such practices were necessary when using open access points. The Comodo rules take care of the usual threats.
