How can I install Internet Guide on my Windows computer?

Enabling the Internet Guide through the Updater (ver 4+) seems to be the easiest method at first, but you should be aware of the following.

In case you enable the Internet Guide in the Updater, it changes the TCP/IPv4 DNS settings of your computer's network connection to the Internet Guide DNS server addresses 216.146.35.35 and 216.146.36.36.

However, setting external DNS server addresses on a local computer breaks local resolution, i.e. you will be facing troubles if you call any other devices in your LAN by name instead of by IP address. You even will no longer be able to call your router by its name.

How to get around this:

• You can append entries for each internal device in your LAN you want to reach by name into the hosts file on those computers, which have the Internet Guide enabled, e.g.

  192.168.0.1   router.box  
  192.168.0.15  office-printer.lan  
  192.168.0.209 sons-pc.lan  

  However, this requires static IP addressing for the devices listed in any hosts file.

• Do not use names, but IP addresses to reach your LAN devices. However, this would also require static IP addressing for the devices, which are to be called, or you had to find out particular IP addresses each time they changed.

• The best approach: Do not enable Internet Guide (e.g. via Updater) on the local devices, but configure the Internet Guide DNS server addresses 216.146.35.35 and 216.146.36.36 on the router or modem instead. This has the advantage that all devices in your LAN use the Internet Guide without any further configuration on single devices, and that local resolution is not broken but still works.

The easiest way to set up Internet Guide is to install the DynDNS Updater for Windows and choose to enable Internet Guide during installation. If you have already installed the client, click the Advanced link in the client interface and check "Enable http://DynDNS.com Internet Guide on this PC" then click Apply.

Once installed you'll find information on configuring it here. The categories are those used by Barracuda and you can lookup domains or IP addresses or report incorrect entries at Barracuda.

Be careful if you install the DynDNS Updater; it will change your DNS settings and it won't change them back if you uninstall it. You will have to fix your network settings manually.
