5.12.1. The source address used in the server-side connection

Routers also define source address and port of the server-side connection. This is the IP address that Zorp uses to connect the server. The server sees that the connection originates from this address. The following two parameters determine the source address used in the server-side connection:

forge_addr: If set to TRUE, Zorp uses the client's source address as the source of the server-side connection. Otherwise, Zorp uses the IP address of the interface connected to the server.

forge_port: This parameter defines the source port that Zorp uses in the server-side connection. Specify a port number as an integer value, or use one of the following options:

NameDescription
Z_PORT_ANYSelected a random port between 1024 and 65535. This is the default behavior of every router.
Z_PORT_GROUPSelect a random port in the same group as the port used by the client. The following groups are defined: 0-513, 514-1024, 1025-.
Z_PORT_EXACTUse the same port as the client.
Z_PORT_RANDOMSelect a random port using a cryptographically secure function.
