Listens on a TCP port and tunnels all connections transparently via an HTTPS proxy

u2nl (u-tunnel, universal tunnel) listens on a TCP port and tunnels all connections transparently via an HTTPS proxy (using the CONNECT command) to the Internet. You do not need another host on the Internet. It only works if the HTTPS proxy allows these CONNECT connections. It can provide a host with full connectivity when everything except the http proxy is blocked by a firewall.
