Нужен tcp server

Подписываюсь на тред.

Redir v.2.2.1

Redir is a port redirector. It's functionally basically consists of the ability to listen for TCP connections on a given port, and, when it recieves a connection, to then connect to a given destination address/port, and pass data between them. It finds most of its applications in traversing firewalls, but, of course, there are other uses. Consult the man page, or run with no options for usage information.
