Configuring static NAT444
Static NAT444 is applicable when the private IP addresses are fixed.
To configure static NAT444:
Step | Command | Remarks |
---|---|---|
1. Enter system view. | system-view | N/A |
2. Create a NAT port block group, and enter its view. | nat port-block-group group-id | By default, no port block groups exist. |
3. Add a private IP address range to the port block group. | local-ip-address start-address end-address [ vpn-instance vpn-instance-name ] | By default, no private IP address ranges exist. You can add multiple private IP address ranges to one port block group, but they cannot overlap. |
4. Add a public IP address range to the port block group. | global-ip-pool start-address end-address | By default, no public IP address ranges exist. You can add multiple public IP address ranges to one port block group, but they cannot overlap. |
5. Configure the port range for the public IP addresses. | port-range start-port-number end-port-number | By default, the port range is 1 to 65535. |
6. Set the port block size. | block-size block-size | By default, the port block size is 256. |
7. Return to system view. | quit | N/A |
8. Enter interface view. | interface interface-type interface-number | N/A |
9. Apply the port block group to the outbound direction of the interface. | nat outbound port-block-group group-id | By default, no port block group is applied to the interface. You can apply multiple port block groups to one interface. |
10. Return to system view. | quit | N/A |
11. (Optional.) Configure a PAT mapping mode. | nat mapping-behavior endpoint-independent [ acl { ipv4-acl-number | name ipv4-acl-name } ] | The default mapping mode is Address and Port-Dependent Mapping. |
