How to configure 1/11 to be dhcp and 1/12 to connect to management PanOS 8.1.10

We have a setup with a network connection into a PA5020 firewall that has a single out interface configured to a Server. Due to configuration (No Switch) we need to be able to access the Management port via one of the unused  ethernet interfaces with a laptop. We can't set the ip of the laptop but can have it pull a DHCP address. The server does not have GUI support loaded. So what i'm trying to do is

Set an interface (1/11) to be a DHCP server and allow connection only to 1/12. We want 1/12 to be a connection to the managment port of the firewall. We want to connect a laptop and access the Management interface via the GUI/Browser. 

Is this possible? I've seen how to set up DHCP and how to use a jumper cable from an interface to the mgt port. But setting the 1/11 and 1/12 to be local /28 ip's i'm getting Virtual router errors when testing the commit. Overlapping ip's. "In virtual-router Management-Router: address 192.168.0.3/28 on interface 1/12 has overlapping subnet with address 192.168.0.3/28 on interface ethernet1/11. (Module: routed)."

I've done the following

Configure 1/11 with 192.168.0.2/28

Configure 1/12 with 192.168.0.3/28

Configure Mgmt-Zone as Layer 3 to include 1/11 and 1/12

Configure Management-Router to include 1/11 and 1/12

Configure DHCP server on interface 1/11 with pool 192.168.0.4-192.168.0.14

I haven't even tried to jumper to the mgt port.

Good Day

I am not sure if I would agree that you NEED to use the Mgt port at all.

If you configure your interface as it is...

Configure 1/11 with 192.168.0.2/28

You can get DHCP from 1/11, but also, you can manage the FW using the 1/11 interface IP.

You would configure an Interface Mgmt Profile to allow things like ping, https, snmp, etc.

This makes your configuration so much easier than what you are attempting.  😛

Will this work... just a single interface for DHCP and managing the FW?

That is one hurdle.... there are more to come.

There are about 20 mgmt services (PANW-DB, Panorama, LDAP, Radius, Dynamic Updates, etc., that are expected to be on the mgt.  You can research Service Routes in the admin guide to change them to use either 1/11 vs mgmt.
