In the last instalation of Kerio, I was able to select what Kerio blocks (Outgoing, Incoming traffic) with each and every application which connected to internet.
Now there is "other applications" which sucks, because between this other applications I have for example StrongDC++ (which I want to UNBLOCK), but other apps I probably would want to block.
I couldn´t find any option how to see it more detailed.
Any suggestions?

Thanx, Forn.

If you have installed SKPF4 in simple mode then all inbound connections will be blocked by default and outbound, permitted. Changing the "any other application" rule to ask, ask, ask, ask will prompt you for both incoming and outgoing connections again.

I have not installed it in simple mode. But the amount of applications working with the internet is not full, some are inside the "other applications" option. How do I get inside it?

Your answer did it. I have to make rules - for each application, but it works. Thanx.

Creating packet filter rules will allow you to define individual ip addresses, ports, protocols, etc. Changing the "any other application" rule will not affect exisiting application rules. These will need to be either changed manually or deleted (to be able to create new rules).
