Firewall traversal from remote host must be disabled
Enables usage of STUN and relay servers when remote clients are trying to establish a connection to this machine. If this setting is enabled, then remote clients can discover and connect to this machines even if they are separated by a firewall. If this setting is disabled and outgoing UDP connections are filtered by the firewall, then this machine will only allow connections from client machines within the local network. If this policy is left not set the setting will be enabled.
