22 * Testcase for port redirection and public IP address retrieval.
23 * This test never fails, because there need to be a NAT box set up for that.
24 * So we only get IP address and open the 2086 port using any NAT traversal
25 * method available, wait for 30s, close ports and return.
26 * Have a look at the logs and use NMAP to check that it works with your box.
