Paloalto Networks PCNSE Exam With Confidence Using Practice Dumps

Set the Action to take when matching a packet:

Forward—Directs the packet to the specified Egress Interface.

Forward to VSYS (On a firewall enabled for multiple virtual systems)—Select the virtual system to which to forward the packet.

Discard—Drops the packet.

No PBF—Excludes packets that match the criteria for source, destination, application, or service defined in the rule. Matching packets use the route table instead of PBF; the firewall uses the route table to exclude the matched traffic from the redirected port.

In a High Availability (HA) setup with Palo Alto Networks firewalls, the synchronization of IPsec tunnel Security Associations (SAs) is an important aspect to ensure seamless failover and continued secure communication. Specifically, for Phase 2 SAs, they are synchronized over the HA2 links. The HA2 link is dedicated to synchronizing sessions, forwarding tables, IPSec SA, ARP tables, and other critical information between the active and passive firewalls in an HA pair. This ensures that the passive unit can immediately take over in case the active unit fails, without the need for re-establishing IPsec tunnels, thereby maintaining secure communications without interruption. It's important to note that Phase 1 SAs, which are responsible for establishing the secure tunnel itself, are not synchronized between the HA pair, as these need to be re-established upon failover to ensure secure key exchange.
