The development of the SCTP NAT automatic test utilities is part of the SONATA[1] project to develop and release a BSD licensed implementation of a Network Address Translation (NAT) module that supports the Stream Control Transmission Protocol (SCTP). The test utilities work with master/slave architecture communicating over a control channel. Tests are specified in configuration files on the master host. This report gives instructions on how tests can be specified, with examples of common SCTP NAT functionality tests.
