Dynamic DNS

Dynamic DNS is used if you have not received a static global IP address from your Internet service provider, but still want people on the Internet to easily find your network or servers. It is especially useful if you want to operate your own web server.

A dynamic DNS service allows people to enter a web-address like http://yoursite.homeip.net and access your web server, even though they do not know your global IP address.

There are many dynamic DNS providers available on the Internet, with different levels of price, service and reliability.

The dynamic DNS client in the Internet Gate can update DNS accounts at:

• dyndns.com
• tekea.com
• telia.com
• tzo.com

To be able to use the dynamic DNS client in the Internet Gate, you need to have such an account at one of the mentioned DNS account providers.

1. From the Network page open Dynamic DNS
2. Decide what provider to use and get an account at them (by clicking on the link on the Dynamic DNS page, opens in a separate window).
3. Enter the same Hostname, User and Password values as you have entered on the dynamic DNS provider's page.

If people accessing your hostname reach the wrong IP address, please check:

1. If your global IP address has been changed recently (less than 5 minutes ago) – it might take 5 minutes or more before your hostname is bound to the new IP address.
2. If your system log states “dyndns.org updated” or if the update resulted in any error.
3. You can manually update your Dynamic DNS account by clicking “Apply” on the Dynamic DNS page.

If your system log reports error “Your dyndns.org hostname is blocked for abuse” or you have received an e-mail from dyndns.org stating the same, read the DynDNS update abuse policy.

Dyndns.org blocks accounts for abuse if you have repeatedly updated the account with the same IP address.

Every time you click Apply on the Dynamic DNS page, an update is sent to dyndns.org regardless of if your global IP address has been changed or not. Clicking Apply excessive amount of times might get your account blocked for abuse.

If you have received an e-mail from dyndns.org stating your account will soon expire due to lack of update, go to the Dynamic DNS page and click Apply to manually force an update of your account.

If an account has not been updated for 35 days, dyndns.org removes it from its lists. The dynamic DNS client in your product updates accounts every 25 days, even if the IP address have not changed. However, the update timing might become disturbed if the product is turned off.

If your IP address has not changed during the last 25 days, it might be a good idea to change your account type into Static DNS. Read more about DynDNS Static DNS service.
