HOW TO Allow interface to access ethernet interface configured as Managment

L1 Bithead

We have a 2 system (firewall and RHEL7 server) configuration that has been set up to allow management access through ethernet1/11. What i am trying very unsuccessfully to do now is configure ethernet1/12 to be able to connect to the managment interface.

1/11 is set up to do DHCP so our laptops can connect for GUI use. I would like the RHEL7 server to be able to connect for cli access through second interface. I have the 11/1 configured with Interfaces 1/11 and 1/12 are in a zone with only those two interfaces. The virtual router is configured with only these 2 interfaces.

I tried to set the 1/12 interface to, but that fails with overlapping subnets. I've tried setting up static routing with the 1/12 interface set to but again it didn't work. Nothing i've tried has worked to allow the ssh connection from the server to reach the firewall interface (1/11) and log in.


Thanks for any help you all can give.

Hello again.


You and I just discussed this last week, regarding DHCP and the Mgmt interface.

Have you configured and enabled an interface management profile on ether1/11?


I have a simple 2 port network, on a PA220 (well, technically 3, if you could count the mgmt interface)


My network is with my management interface using IP of


REGARDLESS of that piece of information.. My ethernet1/2 is the inside of my network, doing DHCP as well.

The Ethernet1/2 IP is It acts as my DHCP server as well.


Anything plugged into my downstream switch can/could SSH into, because I enabled an interface management profile that allows SSH.  This should 100% work.


So I do not understand why the RHEL server cannot simply SSH into your eth1/11.. why must it be connected to eth1/12?

Maybe you can help me to understand that, and then we can move forward.


I know I do not want to make it more complicated for you.. but it really sounds like what you need a 2 port vlan, with a VLAN interface that is doing the DHCP and allowing access to mgmt functionality.


eth1/11  ====\

                       |==> VLAN Interface, supporting DHCP, with interface mgmt profile allowing SSH.

eth1/12 ====/


Or you can create 2 separate networks and then a different network ( and have the virtual router do the routing between them.  


What does your security policy show.  Can you see traffic attempting to pass through the FW?


I am available for a phone call tomorrow (12/31) if you send me a message.  This should have been resolved last week.  😛

Yes, i do appreciate the help. We have no switch and are looking to have the server able to connect to fw for cli access. I really didn't expect any issues after you helped with the DHCP and interface help. That worked perfectly and allowed laptop connectivity for GUI access. I have started the training that is available through Palo Alto to get a better understanding of the fw.

Ok, our setup is admittedly odd. 1 line in to the fw for network. Then the server off of that. No switch or other systems, the server is reachable through a KVM. I am looking to have the connection from the server to the fw be constant. and the laptop connection as needed. Hoping we can do most stuff via the CLI and only use the GUI for more involved issues.

I have tried 2 separate networks, but if that should have worked i did not do it correctly. I will re-try the VLAN answer since that seemed to be a workable solution i just didn't get it working.

You need to configure the mgmt profile which allows ssh and bind that profile to the respective interface.

Sorry about the delay getting back to my thread, got re-tasked for a bit. What i ended up doing to get the systems up was enabling both ethernet1/11 and ethernet1/12 as Management ports. So the DHCP and Management on 1/11 will be for our laptop connection with GUI or CLI access. The 1/12 has Management profile with static IP reachable from the RHEL server for regular access via SSH to CLI.

Any major pitfalls/problems with doing it this way. 

Basically.. you are somewhat good.


Now the mgmt port itself (not /11 or /12) has about 20 services (NTP, Panorama, DNS, Wildfire, etc)


What public facing interface on the FW is going outbound to get updates, such as NTP, DNS, WF, etc, etc?)

1/1 is the incoming connection.
