	How Kaspersky Anti-Virus for protection of personal desktops and workstations version 6.0 co-works with Agnitum Outpost Firewall How Kaspersky Lab products version 6.0 co-works with Norton Personal Firewall 2005 After installation of Kaspersky Lab product version 6.0/7.0 Internet-connection via Wi-Fi has disappeared

This article applies to Kaspersky Internet Security version 6.0/7.0/2009 and Kaspersky Anti-Virus 6.0 for Windows Workstations MP2/MP3/MP4 only if the Anti-Hacker (firewall) component is not installed and is not used together with a firewall of another vendor.

The following problems may occur when a Kaspersky Lab product works with a firewall of another vendor:

• cannot send / receive e-mails
• internet pages are not (fully) loaded
• computer disconnects from Internet either immediately or soon after establishing a connection

The reason is that Kaspersky Lab applications version 6.0\7.0\2009 are functioning in server mode. They re-route all Internet and e-mail traffic to itself in order to scan it and establish Internet connection with server. It is necessary to have correctly configured rules for the service AVP.EXE in the firewall.

• If the installed firewall has a learning mode, enable it. If the AVP.EXE service tries to establish connection, the firewall should inform the user about it. Allow any network activity to the service AVP.EXE. 
• If the installed firewall does not have a teaching mode, create permissive rules for the AVP.EXE process manually for the following system ports:
• Port of the AVP.EXE process: 1110
• Standard HTTP ports: 80, 81, 82, 83, 1080, 7900, 8080, 8088, 3128, 11523
• Standard SMTP port: 25
• Standard POP3 port: 110
• Standard NNTP port: 119
• Standard IMAP port: 143
• Local port: 19780

If port 1110 is closed, the process AVP.EXE will start trying all other ports within the 1110 - 2110 range unitl it manages to find an open one.
