NSX Manager uses certain TCP and UDP ports to communicate with other components and products. These ports must be open in the firewall.

You can use an API call or CLI command to specify custom ports for transferring files (22 is the default) and for exporting Syslog data (514 and 6514 are the defaults). If you do, you will need to configure the firewall accordingly.
