+ If the <local IP> and <local port> are ommitted and the
+ -no-listener option is not given, the boolean variable
+ use_auto_addr will be examined. If it is set the value
+ of auto_bind_ip will be used as the IP address to bound
+ the listener, the value of auto_public_ip will be the IP
+ address sent to the remote client, and the auto_bind_port
+ will be the port value to be bound to and sent to the remote
+ client. If auto_public_ip is unset, but auto_bind_ip is
+ set, SILC client will send the auto_bind_ip variable's
+ value to the remote client.
