The basics for loopback or hairpin nat with dynamic wanip are.

  1. add extra masquerade rule (also needed for fixed/static wanip)
  2. modify dstnat rule according to method desired (no change required for fixed/static wanip)
  3. ensure fw forward chain rules allow dstnat (also needed for fixed/statck wanip)
