1.6.2. Ports to be Allowed for Remote Administration
Ports that need to be allowed for remote administration are listed below:
Communication on TCP port number 80
For downloading AVG updates from the internet to the AVG Admin Server UpdateProxy, it
is necessary to permit outgoing communication for these components on TCP port 80.
TCP Port 4158
For basic communication between the AVG Admin Server and the AVG stations and the AVG
Admin console, you need to allow TCP port 4158 (predefined by default).
This port can be changed in the AVG Admin Server configuration and in the AVG User
Interface on the station (via upper menu Tools/Advanced Settings – Remote
Administration).
TCP Port 6051
This port is used for direct messages from AVG Admin Server to the AVG Station.
This port can be changed within the AVG User Interface on the station (via upper menu Tools/
Advanced Settings – Remote Administration group).
TCP Port 6054
This port is used for direct messages from the AVG Admin Server to the AVG Admin
Console. This port is not configurable. AVG Admin Console tries to open this port
automatically for listening, if the port is not available, it tries to open subsequent ports (6055,
6056, …) until it successfully finds an available one.
