! Since the Internet traffic is using 'nat source' to the active interface IP address,
! a destination policy class is included in the previous NAT policies to control which
! NAT is used. Specifying a destination policy class restricts that policy for use on
! sessions that egress an interface with the specified policy class. This in conjunction
! with 'ip firewall fast-nat-failover allows NAT to adjust quickly when the egress
! interface changes.
