It would be nice to be able to setup nat rules that are not limited to a range, but allow comma delimited ports. E.g. open 22, 80, 443 with one rule entry.
For example, if you want to open http & https to the same machine it currently requires 2 rules.
In addition, you currently cannot edit a rule (change up or port) and have it stick. You have to delete the rule and start over. This also requires multiple soft reboots.
