+/**
+ * Testcase for port redirection and public IP address retrieval.
+ * This test never fails, because there need to be a NAT box set up for that.
+ * So we only get IP address and open the 2086 port using any UPnP and NAT-PMP
+ * routers found, wait for 30s, close ports and return.
+ * Have a look at the logs and use NMAP to check that it works with your box.
