suspend passive

If you suspend a passive firewall in an active/passive HA configuration does it just mean that you have turned off HA and the active cannot fail over to the passive?

Hello,

That is correct.

So if you suspend both firewall does traffic stop passing?

Interesting thought. While I dont want to test it :). My guess would be no, since its just suspending HA. But I could be wrong on that one. I know that if one is suspended (passive) and you reboot the active, traffic stops flowing since there is not a failover partner.

Suspend a firewall in HA basically stop all traffic from going through it, except for the management interface. If you suspend the secondary firewall in an HA pair, then the primary has nothing to failover to. Suspend the primary firewall while the seconday is suspended ... and no traffic will go through, as there are no active interfaces.

Hopefully, you're on the same network segment as the management interfaces at that point. 🙂

@fjwcash

Thanks yes I am on the same segment at the management interface :). I typically use suspend only to failover to the secondary when I am upgrading the primary at this point and I did hear of someone who forgot the secondary was suspended, suspended the primary and oooops stopped all traffice 😮
