Configuring Inline Twice Static NAT44 for Next Gen Services

 

Configuring the Source and Destination Pools for Inline Twice Static NAT44

To configure the source and destination pools for inline twice static NAT44:

  1. Create a source pool.
  2. Define the addresses or subnets to which source addresses are translated.

    or

  3. Configure a one-to-one static mapping of the original source addresses to the addresses in the source pool by specifying the first address from the matching source-address prefix that is in the source NAT rule.
  4. Create a destination pool. Do not use the same name that you used for the source pool.
  5. Define the addresses or subnets to which destination addresses are translated.
  6. To allow the IP addresses of a NAT pool to overlap with IP addresses in pools used in other service sets, configure allow-overlapping-pools.

Configuring the NAT Rules for Inline Twice Static NAT44

To configure the source and destination NAT rules for twice static NAT44:

  1. Configure the source NAT rule name.
  2. Specify the traffic direction to which the source NAT rule set applies.
  3. Specify the addresses that are translated by the source NAT rule.

    To specify one address or prefix value:

    To specify a range of addresses, configure an address book global address with the desired address range, and assign the global address to the NAT rule:

  4. Specify the source NAT pool that contains the addresses for translated traffic.
  5. Configure the generation of a syslog when traffic matches the source NAT rule conditions.
  6. Configure the destination NAT rule name.
  7. Specify the traffic direction to which the destination NAT rule set applies.
  8. Specify the destination addresses of traffic that the destination NAT rule applies to.

    To specify a range of addresses, configure an address book global address with the desired address range, and assign the global address to the NAT rule:

    To specify any unicast address:

  9. Specify the destination NAT pool that contains the destination addresses for translated traffic.
  10. Configure the generation of a syslog when traffic matches the destination NAT rule match conditions.

Configuring the Service Set for Inline Twice Static NAT44

To configure the service set for inline static NAT44:

  1. Define the service set.
  2. Configure either an interface service set, which requires a single service interface, or a next-hop service set, which requires an inside and outside service interface.
    • To configure an interface service set:

    • To configure a next-hop service set:

  3. Specify the NAT rule sets to be used with the service set.

Configuring Inline Services and an Inline Services Interface

To enable inline services and an inline services interface:

  1. Enable inline services for the FPC and PIC slot, and define the amount of bandwidth to dedicate to inline services.
  2. Configure the inline services logical interface or interfaces.
    • If you are using an interface service set, configure one logical unit:

    • If you are using a next-hop service set, configure two logical units and define the inside and outside interfaces:
