Of course, the configurations presented are only a proposal of what can be done. Many options have not been explored, such as a firewall with a scheme similar to 5.2.1 with many services wrapped, inetd-based wrappers, SMTP- and POP3-specific options, etc. However, with this section as an introduction it should be perfectly clear how to set up many different wrappers. Having all this different configuration posibilities makes ProtoWrap a very usable and convenient program, which, although presently is at an early, functioning stage, can soon evolve and become a very useful security tool.
