Prior to Symantec Protection Engine 7.x for NAS and Cloud Services, the Port entry on the Quarantine Server tab had to be set to a value calculated from the reversed hexadecimal dword registry entry for IP Socket found on the Symantec Quarantine Server.
In Symantec Protection Engine 7.x for NAS and Cloud Services the decision was made to correct this issue so that now administrators only need to match the Port value they entered when configuring the Symantec Central Quarantine Server properties. Now both products will be set to the same "Listen on IP" Port value.
Note: Administrators please refer to the following knowledge base document. www.symantec.com/business/support/index to calculate the Port value for use within Firewall rules.
