I've been trying out this firewall for the past couple of days but I think it's more trouble than it's worth. eg although I was directed to this Forum by a Sunbelt reply, I've only just managed to login now having exited Kerio and changing to Int Ex.
My default browser is Firefox and I'm using AVG Pro, Spybot, AdAdaware and Defender with Windows firewall.
I thought I should load a "proper" firewall but since installing Kerio: I was unable to load Windows Live Local(until prompted to disable web filter) and when trying to make an internet purchase today, again I had to disable webfilter before the checkout page would load. I've only just managed to place this post in your forum by exiting Kerio.
Methinks I'll bin it unless someone can point out what Ive been doing wrong!

As you have already mentioned, it looks like the web module is your problem. I haven't used this module myself so I don't know what the default settings are but it may help if you look in the web log for any items being blocked. These will need to be permitted (manually) as site exceptions.

I would go through the motions of using your browser, checking the web log each time (once you hit a problem) and then add the appropriate exception and test again, repeating this untill everything works.

OK thanks.
I'll persevere for a bit and see how I get on.
