                    --  default: SRCIF="*:*:*:*:*"

This parameter is useful for DeleGate running on a multi-homed host or on a host behind a firewall with packet filtering.

This parameter specifies the source address (of a network interface) of each connection to a server. This can be useful when the host of DeleGate has multiple network interfaces. Also it can be used to specify the port to be used for accepting a client connection by a SOCKS-DeleGate or a FTP-DeleGate.

In most cases, a special pattern "*" as host or port specifies the wild-card IP address or port number. In some cases, the special pattern "*" is used for the desired address and number which is specified by a protocol, like a port for FTP data connection (by PORT or PASV) or a port for SOCKS (BIND and UDP-ASSOCIATE). To explicitly specify the wild-card as an IP address and port number, use "0.0.0.0" as host and "0" as port respectively.

Example:

SRCIF="*:0:ftp-data" // use a random port number for FTP data connection
SRCIF="*:8020-8120:ftp-data" // use a port number in the specified range
SRCIF="150.29.202.120:*:tcpbind" // use the specified address to accept via SOCKS
SRCIF="150.29.202.120:*:udpbind" // use the specified address to relay UDP on SOCKS


The port for "ftp-data" connection which is assigned on demand and notified to the peer, that is from client to server by PORT or from server to client by PASV, can be controlled separately by "ftp-data-port" or "ftp-data-pasv" respectively. The source port for data connection, which is established from server to client for PORT or from client to server for PASV, can be controlled by "ftp-data-src".
