This is documentation about a configuration directive, which can be placed within Movable Type’s core configuration file,
mt-config.cgi, to customize the behavior of the system.
By default, outgoing Trackback and update pings are sent to the internet using the default network interface card (NIC) on the server running Movable Type. In some rare cases, it may be necessary or desirable to have the outbound ping traffic sent over a different network interface card or network connection. In these situations, enter the IP address of the network interface card that should be used to send the outgoing ping notifications.
You may specify only the IP address (xxx.xxx.xxx.xxx) or an IP address and port number (xxx.xxx.xxx.xxx:#). If no port number is specified, the outgoing ping will be sent from the specified IP address using the next available port number. If a port is specified, the outgoing ping will be sent from the specified IP address AND port number. This is useful when you need a consistent source IP:port address for firewall filtering of outbound connections.
Don’t specify a port unless it’s absolutely necessary. If the port specified is already in use, the outgoing ping will fail without error.
Default value: none
