Enabling Global Mapping Sharing For Dynamic Nat444; Configuring Ds-Lite Nat444 - HPE FlexNetwork HSR6800 Configuration Manual

Step
5. Configure port block
parameters.
6. Return to system view.
7. Enter interface view.
8. Configure PAT for
outbound dynamic NAT.
9. Return to system view.
10. (Optional.) Configure a
PAT mapping mode.

Enabling global mapping sharing for dynamic NAT444

When multiple interfaces have dynamic NAT444 configured, the interfaces might create different
NAT444 mappings for packets from the same IP address. You can perform this task to configure the
interfaces to share the same NAT444 mapping for translating packets from the same IP address.
To enable global mapping sharing for dynamic NAT444:
Step
1. Enter system view.
2. Enable global mapping
sharing for dynamic NAT444.

Configuring DS-Lite NAT444

DS-Lite NAT444 is configured on the AFTR's interface connected to the external network. DS-Lite
NAT444 supports only dynamic NAT444.
The DS-Lite NAT444 configuration is similar to the dynamic NAT444 configuration. The difference is
that DS-Lite NAT444 uses an IPv6 ACL and dynamic NAT444 uses an IPv4 ACL to identify packets
to be NATed.
To configure DS-Lite NAT444:
Step
1. Enter system view.
2. Create a NAT address
group, and enter its view.
