I installed CFP 3.0.25.378 yesterday. It’s the first time I’ve used Comodo (I switched from Zonealarm) and I’m very pleased with it.
Whenever I connect to the internet (I’ve been using GPRS for about a month while waiting for DSL), CFP detects a new “local area network” (or some phrase like that). Each time, the IP is slightly different — first it was 10.144.102.36. Then 10.142.41.81. Now it’s 10.142.48.2. Apparently, all of these IPs belong to IANA (yes, I know what IANA is).
Why is this happening each time I connect?
And how do I stop it?
This is caused by your ISP allocating a new IP address to you each time you log in.
This can be overcome by defining a new zone based on the IP pool your ISP uses. From the look of the addresses you’ve mentioned in your post, they are using 10.14X.X.X addresses. The entire 10.X.X.X subnet is devoted to private LANs and when you connect, you are, in effect, becoming a node on your ISPs LAN and they are handling the connection to the internet on the far side of your connection.
It is safe to create a zone in the 10.X.X.X subnet, as addresses in this range are non-routable. This means when you have this address, any packets from your PC are sent to your ISPs network, they fudge and fiddle the IP address in the data packet and send it to the internet on your behalf.
