Filter-based approach

A filter-based approach diverts traffic to NAT based on the IP matching criteria shown in the CLI below.

*A:right-a21>config>filter>ip-filter>entry# match 
  - match [protocol <protocol-id>]
  - no match

 <protocol-id>        : protocol numbers - [0..255] (Decimal, 
                                Hexadecimal, or Binary representation).
                        Supported IANA IP protocol names - 
                                none|crtp|crudp|egp|eigrp|encap|ether-ip|
                                gre|icmp|idrp|igmp|igp|ip|ipv6|ipv6-frag|ipv6-icmp|
                                ipv6-no-nxt|ipv6-opts|ipv6-route|isis|iso-ip|l2tp|
                                ospf-igp|pim|pnni|ptp|rdp|rsvp|sctp|stp|tcp|udp|vrrp
                        * - udp/tcp wildcard

 [no] dst-ip          - Configure dest. ip match condition
 [no] dst-port        - Configure destination port match condition
 [no] port            - Configure port match condition
 [no] src-ip          - Configure source ip match condition
 [no] src-port        - Configure source port match condition

The CLI for the filter-based diversion in conjunction with multiple NAT policies is shown below:

filter
    entry
      action nat [nat-policy <nat-policy-name>]

The association with the NAT policy is made after the filter is applied to the SAP.
