Improvements that can be done to NPF with reference to WIP code/descriptions:

- ~~~Import [thmap](https://github.com/rmind/thmap), needed for [newer NPF](https://github.com/rmind/npf/)~~~
- [WIP dynamic NAT address and NETMAP](https://github.com/rmind/npf/pull/9)
- Use of "any"  
  ```map $ext_if dynamic any -> $ext_v4 pass family inet4 from $int_net```.  
  needs a few syntactic fixes/wrappers (e.g. loading can just handle "any" here, since it's actually correct, just merely not supported by the syntax; you can replace it with 0.0.0.0, though)
- traffic redirection, [1](http://www.netbsd.org/~rmind/npf_ext_route.c) [2](http://www.netbsd.org/~rmind/npfext_route.c)
  I think it just needs IPv6 handling and testing
