Can the default Update Cache TCP port of 8191 be modified?

The default Update Cache TCP port of 8191 cannot be modified. This port is specifically designated for the Update Cache features to function correctly within the Sophos environment. Changing the port could lead to communication issues between components that rely on this port for updates and data synchronization.

Sophos configurations typically aim to maintain consistency and reliability of service, and allowing modification of such fundamental settings could create unnecessary complications. Therefore, maintaining the default port ensures that all clients and servers can communicate effectively without additional configuration headaches. Typically, such ports are hardcoded in the configurations to prevent accidental changes that could disrupt services.

While there may be advanced settings available for other configurations within Sophos products, the update cache port remains fixed, thus reaffirming that it cannot be modified under standard operating conditions.
