Failover but Cannot access WebGUI

L2 Linker

Hi All,

 

I tried to upgrade the Palo firewall HA (Active-Passive). But when I failover active to passive, we cannot access the GUI on both firewall. Before I failover, I check the passive cannot reach to updates.paloaltonetworks.com. 

 

After I failover, I tried to connect throught CLI and passive (which it became active) can reach to updates.paloaltonetworks.com. And active(which it became passive), cannot reach to updates.paloaltonetworks.com.

 

Is this the cause that we cannot access the GUI via internet?

 

Need your guys help on this. Thank you.

After failover, I ping both firewall and it have intermittent connection issues. But when I unsuspend, there is no intermittent connection issues.

@Momoj,

From what you've described it sounds like you aren't using the management interface and you have a management profile setup on a loopback interface or another dataplane interface. Likewise, it sounds like you have a service route configured on the device, which would make sense if you don't have the management interface connected.

If that's the case everything you described in your post makes sense. Service routes through dataplane resources aren't going to be accessible unless the device has the active role. Likewise access to the passive device isn't going to function if you are using a management profile on a dataplane interface. It sounds like everything you've described to this point is expected behavior working under the assumption that I've stated above.

 

If you actually have the management interface plugged in on both devices and you aren't using service routes, please report that. I'm making some assumptions based off of what you've said that may not be correct, but account for the behavior that you're reporting. 

Hi, the management interface is plugged in for both device. Thank you for your help. I already logged ticket to TAC support.

Which PAN OS version are you using?

Did this happened first time?

 

Do you enabled MGMT interface as HA1 backup also?

Let us know what TAC says?
