The na-dispute server command configures the mapping table of interval servers.
The undo nat-dslite server command clears the previous configuration.

| Parameter | Description | Value |
|---|---|---|
server-id |
The ID of server. |
The value is an integer ranging from 0 to 511. |
global-address |
Refers to the IP address (a public network IP address) for the access of external hosts. |
The value is in dotted decimal notation. |
host-address |
Refers to the internal IP address of the server. |
The value is in dotted decimal notation. |
protocol-type protocol-number |
Refers to the type and number of the protocol over IP. |
The value can be 1, 6, 17, 41, 47, 50, or 51 if it is entered in the format of an integer. The value can be tcp, udp, sctp or icmp if it is entered in the format of a name. |
global-port |
Specifies a port for external accesses. |
If the value is entered in the format of an integer, the value ranges from 0 to 65535. When the value is 0, it indicates that any port number is applicable. If this parameter is not entered or the any parameter is entered, it indicates that any port number is applicable. |
host-port |
Refers to the number of service port provided by the server. |
If the value is entered in the format of an integer, the value ranges from 0 to 65535. When the value is 0, it indicates that any port number is applicable. If this parameter is not entered or the any parameter is entered, it indicates that any port number is applicable. |
unr-route |
Delivers the UNR route to prevent routing loops. |
By default, no UNRs are delivered. If global-address is the WAN interface address, UNRs are not required. |
cpe cpe-ip |
Specifies the IPv6 address of the remote family gateway (or CPE). |
- |
tunnel tunne-number |
Specifies the ID of the DS-Lite tunnel connected to the remote family gateway (or CPE). |
The value is an integer ranging from 0 to 1023. |
virtual-router-id |
Specifies the ID of a VRRP backup group. |
It is an integer that ranges from 1 to 255. |
zone-name |
Specifies the name of a security zone. |
It is a string of 1 to 32 case-insensitive characters, starting with a letter from a to z or A to Z. |
description text |
Specifies the description of the nat-dslite server. |
The value is a string of 1 to 31 characters, which can be blank spaces. |
When multiple internal servers advertise to the external networks with the same public IP address, you can run the na-dispute server command for several times, but the global ports are different. When you configure the nat-dslite server protocol command, if one of global-port and host-port is defined as any, the other must be defined as any or left undefined.
If the nat-dslite server command is used but no UNR is configured, run the nat-dslite server server-id unr-route enable command and keep other configurations unchanged. In this manner, users can flexibly configure UNRs.
