Can you use DHCP reservation information to map USER-ID?

Can you use DHCP reservation information to map USER-ID?

Weird question....but have to ask.


Small Office network


Use PA220 as a DHCP Server for users (even mobile devices).

DHCP Reservation Table has all the information that I think USER-ID could there a way to make this happen?


thought about trying to forward a log file out of Management Interface to the Trusted interface.....but just spitballing here.


Bottom line - trying to come up with a way that I don't have to make users authenticate (so to speak).


Like I said....weird question :-)

Check out the following:


I'm sure there is a location where all users must authenticate to? If not then Captive Portal and /or Global Protect might be the way to go.


Just some thoughts.

@thartman I don't think that this will work.

The DHCP DORA process has no user information involved - so how should the firewall map that IP to a user?

I would recommend to use internal globalprotect for UserID - that's the best reliable source for it - in the meantime, youcould use WMI probing
