STUN provides a means for applications to discover the presence and type of firewalls or NATs between them and the public Internet. In the presence of a NAT, STUN can also be used by applications to learn the public Internet Protocol (IP) address assigned to the NAT.

There is a plugin for AMaViS and several mailservers to scan all EMail going through a mail server.
QDPF was written to solve the problem of exposing internal services to the Internet. It runs on machines which bridge two networks and forwards TCP/IP packets from one to the other. Its main use is to expose corporate or Intranet services to the Internet, by running it on an intervening machine. TCP sessions can also be followed in detail using the 'trace' option. QDPF is a Java console application.
