At the first string we create a TCP server at port 9000 in background mode (look that command ends with '&' symbol). Next, we set IP addresses for our local tun interface to match peer ip address parameters (first and second addresses match at peer and localhost). Techniques: manually paint an (unrouted) ip4/ip6 header, or apply and fix up a vnet_rewrite_t from the session object. Then we run an ssh session to our own host with options that redirect connections incoming to local port 5000 to remote host 9000. The Linux GTP tunnelling module. Next string we use ifconfig utility to set up some internal addresses for remote tun-s and turn it on. ANY over GRE over IP.
