LISTEN_INTERFACE_ADDRESS

(string, "INADDR_ANY" or dotted decimal IP address) The IP address of the network interface to listen to for inbound SMPP client connections. May be either the string “INADDR_ANY” (all available interfaces) or an IP address in dotted decimal form. (For example, 193.168.100.1) The default value is “INADDR_ANY”. Clustered HA configurations will need to set this value to correspond to the HA logical IP address.
