6-6 Advanced Configuration of the Gateway
Respond to Ping on Internet WAN Port
If you want the gateway to respond to a 'ping' from the Internet, click the ‘Respond to Ping on
Internet WAN Port’ check box. This should only be used as a diagnostic tool, since it allows your
gateway to be discovered. Don't check this box unless you have a specific reason to do so.
Dynamic DNS
If your network has a permanently assigned IP address, you can register a domain name and have
that name linked with your IP address by public Domain Name Servers (DNS). However, if your
Internet account uses a dynamically assigned IP address, you will not know in advance what your
IP address will be, and the address can change frequently. In this case, you can use a commercial
dynamic DNS service, who will allow you to register your domain to their IP address, and will
forward traffic directed at your domain to your frequently-changing IP address.
The gateway contains a client that can connect to many popular dynamic DNS services. You can
select one of these services and obtain an account with them. Then, whenever your ISP-assigned
IP address changes, your gateway will automatically contact your dynamic DNS service provider,
log in to your account, and register your new IP address.
From the Main Menu of the browser interface, under Advanced, click on Dynamic DNS. To
configure Dynamic DNS:
1. Access the website of one of the dynamic DNS service providers whose names appear in the
‘Select Service Provider’ box, and register for an account.
For example, for dyndns.org, go to www.dyndns.org.
2. Select the Use a dynamic DNS service check box.
3. Select the name of your dynamic DNS Service Provider.
4. Type the Host Name that your dynamic DNS service provider gave you.
The dynamic DNS service provider may call this the domain name.
5. Type the User Name for your dynamic DNS account.
6. Type the Password (or key) for your dynamic DNS account.
7. If your dynamic DNS provider allows the use of wildcards in resolving your URL, you may
select the Use wildcards check box to activate this feature.
For example, the wildcard feature will cause *.yourhost.dyndns.org to be aliased to the same
IP address as yourhost.dyndns.org
