Management IP in Active/passive setup

L1 Bithead

Hi 

 

I am quite new to Palo Alto firewalls, but have worked with different vendors before. 

 

When running a HA in Active/passive a central VIP for mgmt is usually setup, so you dont connect to the passive FW.

From what i see there is no VIP for mgmt in the HA setup i am working on here. Is that something that is setup wrong or ? 

We have a dns name internally that points to one of the firewalls, but in case of failover this might end up being the passive node. 

 

hope someone can enlighten me.

Would you means you want to access current active firewall in same IP independent of which take a active?

 

You can set a loopback interface and set it permits for management traffic.

Since the passive firewall data-port will not turn on, you will always access to the current active firewall through that loopback interface IP.

You are correct.
Palo Alto firewalls in HA need their own separate management IPs.

So that how are people handling the management in a failover case ? just change the DNS entry or this there something easier ? 

In most cases, each node has its own DNS name. In my lab, for example, I have

https://palo-pri.kiki.lab

https://palo-sec.kiki.lab

It's designed this way for a number of reasons, including so that each node can have its HA status controlled, reach out the internet for updates, telemetry forwarding, forward Syslog to external servers, etc.

Hello @hh_cloudio ,

What is the use case you are attempting to resolve? Just connecting or something else, more curious than anything?

 

Regards,

Just so in case of a failover that you allways connect to the active firewall. Its not a issue, i am just used to management via. a VIP so you allways connect to the active firewall.
