active server and passive client

[Constantine Shulyupin]

Hi colleagues,

I have: servers (HTTP, FTP, RTSP and other) behind firewall and a
client PC. The client wishes to connect to severer. But firewall
doesn't allows him to connect to server.

The server knows the clients IP and can open a connection.
Unfortunately I can't set up tunneling/VPN on client because of system
administration limitation.

Theoretically, I can rewrite inetd to make connection to client and
rewrite FTP client to listen for connection from server or code custom
protocol.

The question is, is there already ready solution for the task or is
there simple solution than described?

Thank you.
