<div style="direction: ltr; font-size: 11pt;">Hi Ronald,<br>
<br>
I am uncertain if this can be used in the data field, but there is a<br>
concat() in Kea:<br>

<br>
You can use a '+' sign as a shortcut so you might be able to do something like:<br>
<br>
"data": "'s=xx.xx.xx.xxc='+option[82].option[1].hex"<br>
<br>
but I've never tried to use these functions or packet contents in the<br>
"data" field.<br>
<br>
Thank you,<br>
