Dynamic DNS Bind server updates from DHCP

L0 Member

Curious if the PA-3220 we are looking to use can dynamically send DNS updates to our Bind9 server whenever a DHCP request is granted from our PA DHCP scope we've setup? I know we can get a linux version of DHCP on our Linux server, but would rather leverage the gui of the Palo for DHCP.

 

We are not a windows environment so windows DHCP and DNS is not an option.

@tfleming,

This isn't an option when your using the firewall's built-in DHCP Server capability.

Hey @tfleming ,

 

I would agree with @BPry  that there is no native way to achieve this.

However I think you could be creative with some additional scripting.

One way I can think of is:

- DHCP lease is logged in firewsll system logs

- Set log forwarding  (device -> log settings -> system log), filtering for event "lease-start"

- Set action either syslog or HTTP

- Forward the log to Linux machine which can parse the log and carve out the ip address and the hostname
