As per my understanding, the DHCP Option 119 - Domain Suffix Search Lists are not supported by the PAN OS as of now. There are 2 feature request already submitted for adding more DHCP options into PAN OS as mentioned below:
Ability to support custom DHCP options within PANOS DHCP Server.
I would recommend you to contact with your Palo ALto SE for the same.
This is certainly supported now.
Can you probide more details on what you would like to do and what's not working?
I have 3 domains that I'd like to add to my dhcp client domain search list. They are internal company domains so I will use the generic ones below for this example.
I'm using my PA850 as a dhcp server.
I added option 119 as a custom option. I first chose the hex value approach and used an ASCII to hex converter to add these domains as comma separated values. This is how it is done on some Cisco devices. That didn't work on my Windows 10 dhcp client. If I do an ipconfig /release and an ipconfig /renew I get my addresses, my multi-value option 6 DNS server list but nothing for domain search list.
I then tried one hex value per line. That did not work.
So I removed the values and reapplied them as ASCII as one per line, not comma separated. That didn't work either. There's no error when I do the commit. Everything is accepted. But the client doesn't pick up the suffix list.
The I tried to use ASCII with the three domains on a single separated by commas. That didn't work.
So I'm at a loss. Any advise you can provide would be appreciated.
