About Untangle Server's Hostname
Hostnames are needed to identify devices on the network. By default, the Untangle Server's hostname is untangle.example.com. The idea is for you to replace this name with a hostname of your choosing. Make sure that the hostname resolves publicly.
Configuring Untangle Server To Use Dynamic DNS
If your Untangle Server receives a dynamic IP address from your ISP (as opposed to a static IP address), consider using Dynamic DNS. Dynamic DNS enables the Internet to translate a dynamic IP address to a static hostname. Without Dynamic DNS, you must update your Untangle Server's network configuration each time your ISP changes the IP address of your Untangle Server.
A hostname is also useful when you use Quarantine Digests because this feature embeds URL information into its report(s).
To specify Dynamic DNS for the Untangle Server:
Before You Begin:
- Retrieve the Untangle Server's external IP address. Go to Determining Untangle Server's External IP Address.
- Request a hostname for your Untangle Server. Register with a Dynamic Domain Name Service (DDNS) vendor such as DynDNS at http://www.dyndns.com. Complete the service provider's registration, and record the following information, which you need to configure the Untangle Server as shown in Figure, Configuring Untangle Server To Use Dynamic DNS:
- Account Name. Account name that you used to register for the dynamic DNS service.
- Password. Password that you used to register for the dynamic DNS service.
- Host Name and Domain Name. The Internet host name and domain name that you registered with the DDNS service provider.
Caution: Do not download and configure any third-party dynamic DNS clients (for example, the DynDNS Client Updater). The Untangle Server has its own client. If you install DynDNS Client Updater, that client will conflict with the Untangle Server's dynamic DNS client.
- From the Navigation pane, choose Config > Networking.
- Click the Hostname tab.
- Do one of the following:
- (Standard Mode) In the Hostname field, type the hostname that you registered with your dynamic DNS service provider. If you have more than one hostname, you must be in Advanced Mode to list more than one hostname.
- (Advanced Mode) In the Hostname field, type the hostname(s) that you registered with your dynamic DNS service provider.
- Select the Enabled check box, specify your dynamic DNS service provider, then type your account information. Congratulations! You should now be able to contact your Untangle Server from the Internet using its hostname.
