TODOs, in anarchistic order:
============================

- support for configuration file!


- 2.2.x kernels:
  make use of the portfw.so (ipmasqadm package) to create forwarding
  tunnels for incomming data streams
  How to determine when finished? Is it possible to keep it stateless?

- Is there a possibility to open up an masquerading tunnel by
  a userspace program on the firewall?
