Feedback> Can I restrict use of the proxy to a set of nominated IP addresses?
Yes, we added an access control file in Version 2.0. But before you use it please consider why you want to do it. If the reason is security, it probably means you need a firewall. The listen-address option provides a way of binding the proxy to a single IP address/port. The right way to do this is to choose a port inside your firewall, and deny access to it to those outside the firewall. The Internet Junkbuster is not a firewall proxy; it should not be expected to solve security problems. For background information on firewalls, see Yahoo or a magazine article or these well-known books: Firewalls and Internet Security: Repelling the Wily Hacker by William R. Cheswick and Steven M. Bellovin or Building Internet Firewalls by D. Brent Chapman and Elizabeth D. Zwicky. There’s free Linux software available, and a large number of commercial products and services. For an excellent security overview, primer, and compendium reference, see Practical Unix and Internet Security by Simson Garfinkel
