Dynamic NAT
Dynamic Port Address Translation. Dynamic PAT lets multiple outbound sessions appear to originate
Dynamic PAT
from a single IP address. With PAT enabled, the security appliance chooses a unique port number from
the PAT IP address for each outbound translation slot (xlate). This feature is valuable when an
cannot allocate enough unique IP addresses for your outbound connections. The global pool addresses
always come first, before a PAT address is used. See also NAT,

Failover lets you configure two security appliances so that one will take over operation if the other
failover, failover
mode one fails. The security appliance supports two failover configurations, Active/Active failover and
Active/Standby failover. Each failover configuration has its own method for determining and
performing failover. With Active/Active failover, both units can pass network traffic. This lets you
configure load balancing on your network. Active/Active failover is only available on units running
in multiple context mode. With Active/Standby failover, only one unit passes traffic while the other
unit waits in a standby state. Active/Standby failover is available on units running in either single or
multiple context mode.
