The article applies to all Image Server, Maxx and TSS video servers.
For security reasons, a secure tunnel, such as a VPN connection, it highly recommended when remotely accessing the server. If a secure connection is not possible, the following ports may be opened in the firewall to allow connection to the server.
Remote GUI — TCP Protocol – Open ports 10010, 10014, 10016 (probably only 10010 needs to be left open).
FTP — TCP Protocol – Open port 21 (This is not required for Remote GUI, only File Transfer).
Note: Older servers (Image Server & Maxx) utilize an anonymous FTP connection which cannot be changed. This poses a security risk and therefore this method should not be utilized for external connection.
