R3303-HP 6600/HSR6600 Routers Layer 3 - IP Services Command Reference

When an ACL rule is not operative, no new NAT session entry depending on the rule can be created.
However, existing connections are still available for communication.
You can bind an ACL to only one address pool on an interface. An address pool can be bound to
multiple ACLs.
In stateful failover networking, make sure you associate each address pool configured on an interface
with one VRRP group only. Otherwise, the system associates the address pool with the VRRP group
having the highest group ID.
For some devices, the ACL rules referenced by the same interface cannot conflict. That is, the source IP
address, destination IP address and VPN instance information in any two ACL rules cannot be the same.
For basic ACLs (numbered from 2000 to 2999), if the source IP address and VPN instance information
in any two ACL rules are the same, a conflict occurs.
Examples
# Configure NAT for hosts on subnet 10.110.10.0/24. The NAT address pool contains addresses
202.110.10.10 through 202.110.10.12. Assume that interface Serial 2/1/0 is connected to the Internet.

# Configure address pool 1.
[Sysname] nat address-group 1 202.110.10.10 202.110.10.12
# Use addresses in address pool 1 as translated addresses and TCP/UDP port information.
[Sysname] interface serial 2/1/0
[Sysname-Serial2/1/0] nat outbound 2001 address-group 1
# Use addresses in address pool 1 as translated addresses without using TCP/UDP port information.

[Sysname-Serial2/1/0] nat outbound 2001 address-group 1 no-pat
# Use the IP address of interface Serial 2/1/0 as translated address.

[Sysname] interface serial 2/1/0
[Sysname-Serial2/1/0] nat outbound 2001
nat outbound static
Use nat outbound static to enable static NAT on an interface, making the configured static NAT
mappings take effect.
Use undo nat outbound static to disable static NAT on the interface.
Syntax
nat outbound static [ track vrrp virtual-router-id ]
undo nat outbound static [ track vrrp virtual-router-id ]
