Configure DNS

Now to setup the DNS portion. WPAD will take the domain name given to the machine, likely assigned by DHCP, and prepend wpad.. If the domain is example.com, it will look for wpad.example.com. This task may be accomplished with the DNS Forwarder/DNS Resolver on the AZTCO-FW router or with another internal DNS server used by client PCs.

A client browser will ultimately try to access http://wpad.example.com/wpad.dat – among others. More details on the hostnames tried by WPAD are available in the WPAD article on Wikipedia.

To add the entry using the DNS forwarder on the AZTCO-FW router, navigate to Services > DNS Forwarder. Click +  to add a new Host Override.

Enter the following (Replace the domain and IP address with their actual values):

• Host: wpad
• Domain: example.com
• IP Address: 192.168.1.1
• Description: WPAD Autoconfigure Host

Click Save.
