Which firewall rule needs to be created to allow Server Discovery to work in ACS?

Since AXIS Camera Station version 4.30, Server Discovery allows any ACS server with version 4.30 and above to be displayed automatically in the "remote server" combo box on the log on page, new connection dialog and when adding servers to server lists.

Server Discovery is using SSDP and a firewall rule needs to be created in order to get the discovery to work correctly. During a new installation, the rule is added to the Windows Firewall automatically. During upgrade, the rule is added automatically from ACS 4.31.

The firewall should allow inbound connections on the server for ports 55752, 55753, 55754 and 55755.

Configuration example with Windows Firewall on Windows 7:

  • Go to Control Panel > Windows Firewall > Advanced settings
