Hi Ronald,
I am uncertain if this can be used in the data field, but there is a
concat() in Kea:
https://kea.readthedocs.io/en/kea-2.6.1/arm/classify.html#concat
You can use a '+' sign as a shortcut so you might be able to do something like:
"data": "'s=xx.xx.xx.xxc='+option[82].option[1].hex"
but I've never tried to use these functions or packet contents in the
"data" field.
Thank you,
Darren Ankney
