Hi Dan,

I have several questions, please find them under the quoted text:

Do you fetch the data using ext. script?

You approach is clear, but what I don't like is that you clear the whole
table at the beginning and then create instances according to your
current state. So, if you have for instance 10 port mappings active and
you want to add one more, you first delete these 10 and then create
these 10 again plus one new instance, which is much more work than required.

Two questions to give it a try:

1. When and how do you execute this preset? In my case the trigger for
action should be an API call with whatever parameters will be required,
how can I run a preset triggered by  an API call, not an event from
network (BOOT, INFORM, etc)?

2. Even if I use your solution I still don't understand how can I output
PortMapping table on device summary page. That was my second point when
I explained why I bet for virtual parameter approach. Any ideas?

At the end, thank you very much for your input, it really helps.

Best regards,
