!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.
