Guy,
I received my NETIO-230A today. I upgraded to a newer firmware (2.33), and now you can enter a web port number.
Note for anyone doing so: there is a major bug that causes it not to allow you in the box after the upgrade.
You need to use IE instead of Firefox to get in. If this still does not work, you need to so a hardware reset
by turning the box off, then hold in the two buttons on the front panel while turning it on, keep holding
and waiting until you hear two beeps. Then you can log-on with admin / admin under IE (not Firefox).
A bit of a pain, sorry, but this gives you an inexpensive 4-port IP power strip that works the way you want it to.
