It seems every time I restart my PC that Comodo adds a new network zone; it just keeps counting up. When my vpn switched from tap to tun adapter, this seemed to stop. Unfortunately, now that I have heard that CIS doesn't support or filter through a tun adapter, I had to switch to the OpenVPN protcol on my VPN. It is currently up to Home #27. Strangely, it leaves all the previously used Home networks in the list not to be used again unless I go and delete them. 1-27 and tomorrow it will be on to #28.
