USG2100/2200/5100 BSR/HSR &
USG2000/5000 Configuration Guide: Configuring the DNS for Huawei Symantec
When the device serves as the DDNS
client, the DNS server can dynamically update the mapping between domain names
and IP addresses after notified by the DDNS service provider, ensuring correct
IP addresses being resolved from domain names.
Enabling the DDNS
Enabling the DDNS enables other related
DDNS functions. Although you can perform related DDNS configurations in the
case of DDNS disabled, the configurations do not take effect.
Step 1 Choose Network > DNS > DDNS.
Step 2 Select the Enable check box corresponding to DDNS in Configure DDNS.
Step 3 Click Apply.
If the Operation
succeeded dialog box is displayed, the function
is successfully enabled.
----End
Creating a DDNS Policy
A DDNS policy is a collection of such
information as the DDNS server address, login user name, password, DDNS client
domain name, and bound interface. The same DDNS policy can be bound to
different interfaces, which simplifies the DDNS configuration.
Step 1 Choose Network > DNS > DDNS.
Step 2 Click Add in DDNS Policy List.
Step 3 Enter or select the parameters
Step 4 Click Confirm.
If the operation succeeds,
the new configuration is displayed in DDNS Policy List.
Repeat the previous
operations to create multiple DDNS policies.
Modifying a DDNS Policy
Step 1 Choose Network > DNS > DDNS.
Step 2 Click of the line where the entry to be modified resides.
Step 3 Enter or select parameters. Policy Name cannot be modified.
Step 4 Click Confirm.
If the operation succeeds, DDNS Policy List is displayed on the page and data in the list has changed
with the configurations.
However, the configuration
in Password is invisible in DDNS Policy List.
----End
Viewing the Status of the
DDNS Policy
In the case of the DDNS
function enabled, if the DDNS policy is bound to an interface, the
interface automatically
initiates the update request to the DDNS service provider. When the IP address
of the interface changes, or the status of the interface changes, the interface
initiates the update request to the DDNS service provider again.
With the DDNS policy
status, you can learn about the dynamic update of the mapping between IP
addresses and domain names on the DNS server.
Step 1 Choose Network > DNS > DDNS.
Step 2 View Status of the corresponding DDNS policy.
Deleting a DDNS Policy
Step 1 Choose Network > DNS > DDNS.
Step 2 Select the check boxes of multiple entries or the check box in the table
header for selecting all.
Step 3 Click Delete.
If the operation succeeds, the entries
that are just selected are not displayed in DDNS Policy List.
