APPENDIX B

Required ports

In order to maintain a high level of security, you should disable all unnecessary ports. The only ports required by VTL are:

■TCP port 11576 ‐ Used for VTL Console to VTL Server management communication.

■UDP port 11577 ‐ Used for IP replication.

■UDP port11578 ‐ Used for encryption.

■UDP port11579 ‐ Used for encryption.

■TCP port 11580 ‐ Used for communication between a failover pair.

■UDP port 161 ‐ Used for SNMP traps.

■TCP port 161 ‐ Used for SNMP traps.

■TCP/UDP port 3205 ‐ Used for iSCSI.

■TCP port 3260 ‐ Used for iSCSI.

Although you may temporarily open some ports during initial setup of the VTL server, such as the telnet port (23) and FTP ports (20 and 21), you should shut them down after you have done your work.
