The following problems may occur when Kaspersky Anti-Virus 2015 is used along with a firewall of another vendor:

If the firewall you are using does not have a training mode, create permissive rules for AVP.EXE manually.
System port rules:
Ports used by popular applications (ports specified in the applications' preferences may differ):
If after creating permissive rules an application informs you of a connection error, open your firewall's settings and create permissive rules for the exact port the application is trying to use.
