Tool for tunneling IPv4 TCP connections to hosts behind firewall. Has little to do with performance or good coding practices.

Build with cmake:

git clone https://github.com/szpght/nonlocality.git
cd nonlocality
cmake .
make
cp src/nonlocality-server src/nonlocality-client /somewhere/convenient

nonlocality-server <tunneled port> <control port> <data port>
nonlocality-client <server ip> <dest ip> <tunneled port> <control port> <data port>

All connections to server at <tunneled port> will be forwarded to client and consecutively to <dest ip>:<tunneled port>. <control port> and <data port> are used for communication between server and client.
