# TCP Access

Click on “System Configuration”->”TCP Access”.

 The TCP Access feature is a TCP client that attempts to keep a socket open to a server at all times, thus allowing access through firewalls. When Timed Restart is enabled, a valid command must be received at least every 60 seconds, or the socket will be closed and reopened.

 This feature is not used and must be disabled.
