* To make it work, an internal interface and an external interface are defined, where

- * When forwarding the outgoing packet on the internal interface, a simple NAT mechanism

- * e.g. 192.168.1.1:1234 -> 8.8.8.8:80 will be translated into 8.8.8.8:1234 -> 1.2.3.4:80.

- * have a different hallucination that the request is sent from a remote client at 8.8.8.8,
- * to a local address 1.2.3.4.

- * And a NAT mapping is created at the time when the outgoing packet is forwarded.
