startup

File startup is executed when NAT32 starts. It must be located in the current directory and can contain any sequence of valid shell commands. The default startup file contains the following commands:

#

NOTES

NAT32 first makes a local copy of file startup and then actually executes that copy. The copy is deleted on exit.

NAT32 can execute data supplied by any open device.

In particular, if that device supplies the sequence #!tcl as its first line, a Tcl interpreter is invoked to execute the remaining data.
