The icon you’re clicking to disconnect… are you referring to your network connection icon, and that you’re disabling it, then re-enabling to reconnect?
I just took that route, on the chance that’s what you’re doing. I had no problem. Although the network icon did disappear (I would tend to think that’s an issue separate from CPF, but who knows…). But here’s something…
When I re-enabled the network, I got a CAVS HIPS popup notifying me that the network card driver was trying to connect. If I stopped it, I wasn’t allowed to connect. Allow it, and I could. This is interesting to me because I don’t get that driver alert any other time. Now that’s CAVS and not CPF, but it makes me think that something different is happening on your system when you re-enable the network, which may be blocked by some rule you have in CPF (a network rule, application rule, or component rule).
All my services are set to manual (as noted by TheTOM_SK), so I don’t think that’s the issue.
When you installed, did you choose the automatic setup? Have you changed any default rules? Did you run the Trusted Application and Trusted Network Wizards? Do you have logging turned on? If so, what do your firewall logs say at the time your connection can’t be opened/restored?
gfeiner, I really think yours may be a different issue, as it relates to VPN (although there may be some similarities). A quick search on VPN (I didn’t even look for PTTP) says you may have to set up a trusted application rule for your VPN app, define specific ports for it, etc.
The questions in blue are for both of you; it may help clarify (If CPF is blocking some connection - others have found resolution that way - then that may clear it all up). I also suggest that you search the forum (use Advanced Search to eliminate all but just Firewall-related results) for others with the same problem - if you haven’t already. If nothing else, you can file a support ticket to see what Comodo says. http://support.comodo.com If you do so, please post the solution for others’ benefit.
Hope this helps point you in the right direction; I’m glad to help all I can, as are others.
PS: I’m also using Firefox (although I don’t think that’s it, either…)
