In order to allow remote support and management, 
VMWare integration and snapshot replication, SynetoOS uses a set of TCP ports.


Inbound Ports

SynetoOS 5 does not need any ports opened from the internet towards the appliance to have a functioning support tunnel when enabled and access to software updates. 

You need to setup port forwarding only when configuring snapshot replication between two HYPER appliances in different locations and you are not using VPN between the two sites.


Outbound Ports 

To provide the basic range of features, SynetoOS 5 should be allowed to connect to the ports and destinations listed below.
