Hello,

Do you have security rules allowing the traffic through and if so do you see the traffic in the traffic logs of the firewall? If you see the traffic logs do you see bytes received?

I would run a pcap on the DHCP server to see if you see the traffic hitting the server in the first place, if not it may be a routing issue.

I would also check the global counter on the firewall filtered for your DHCP server and see if anything is being dropped. Instructions on checking global counters can be found here: How to check global counters for a specific source and destinat... - Knowledge Base - Palo Alto Networks

Let me know if that helps!
