1# map all tcp connections from 10.1.0.0/16 to 240.1.0.1, changing the source
2# port number to something between 10,000 and 20,000 inclusive.  For all other
3# IP packets, allocate an IP # between 240.1.0.0 and 240.1.0.255, temporarily
4# for each new user.

10# For example, to redirect FTP connections through this box, to the local ftp
11# port, forcing them to connect through a proxy, you would use:
