Entering Required Firewall Settings

In an environment with firewalls, the vCenter, ESX servers, Virtual Server agent, and MediaAgent must be able to communicate with each other. To ensure that all components can communicate through the firewall, ensure that the ports for web services (default: 443) and TCP/IP (default: 902) are opened for communication on each of these machines. 

When a firewall is used, you must open ports on the firewall for all components that are used for features such as Live Browse, Live File Recovery, and Live Mount. These settings are required in addition to normal SnapProtect firewall configuration. The following components require open ports:

  • vCenter
  • ESX server used to mount the snapshot
  • MediaAgent that performs a backup (where the 3dnfs service is running)
  • Virtual Server Agent proxies

Note: If IPV6 support is enabled on the ESX server and the MediaAgent where 3dfs is running, IPV6 will be used to communicate for browse and restore operations.

Port Requirements

The following ports must be opened:

Port Protocol Description From To
2049 (TCP) NFS The 3DFS server listens on this port for NFS remote procedure calls (RPCs). The ESX server connects to the 3DFS server on this port. ESX server
 
MediaAgent performing backup
 
MediaAgent performing backup ESX server
111 (TCP+UDP) SUN RPC PortMapper This port is used by the ESX server to find the mount and NFS ports used by the MediaAgent performing the backup. ESX server
 
MediaAgent performing backup
 
MediaAgent performing backup ESX server
User specified port (TCP) Mount The mount server runs on this port, and the ESX server mounts an NFS share using this port.

In a firewalled environment, you must open a fixed port in the firewall.

If no port is configured, a random port is used, and a different port might be used each time the service is restarted.

902 VMware NFC The MediaAgent performing the backup communicates with the ESX server through this port. MediaAgent performing backup ESX server
443 SSL The MediaAgent performing the backup communicates with the ESX server and vCenter through this port. MediaAgent performing backup ESX server and vCenter

Procedure

Open all of the following ports:

  1. Open port 2049 for the TCP protocol.
  2. Open a user defined mount3 port for the TCP protocol. Create the nMount3Port additional setting on the MediaAgent where the 3dnfs service is running and specify any free port number as the value. After creating the additional setting, restart services.
  3. Open port 111 for both the TCP and UDP protocols.
  4. For the MediaAgent, open the same ports that are used in the firewall configuration for the VMware Virtual Server Agent.
