7.Set up your VPN connections using Auto Detect. If you do not know your ISP connection, Auto Detect will attempt to automatically detect your connection type by probing for different connection methods. If you know your ISP type, you can set up your connections manually.

(Ensure that you have the ISP information relevant to your connection type before you begin.

Using ADSL Microfilters (optional)

ADSL technology uses the same wires as your telephone service. However, ADSL adds signals to the telephone lines which create noise in the telephone service. You must use ADSL microfilters to filter out these signals before they reach your telephone. If you are planning on using the ADSL modem port, and an ADSL Microfilter is not included with your ProSafe DGFV338, you should acquire one.

There are two types of ADSL Microfilters: a one-line filter and a two-line filter with splitter.

•One-Line Microfilter. A simple microfilter provides an interface filter between your telephone and the phone jack as shown in Figure 2-1. Each device such as a telephone, fax machine, answering machine, or caller ID display requires an ADSL microfilter..

Figure 2-1

You can also connect the one-line filter to a phone-jack splitter to allow for connection of the wireless firewall. However, the phone-jack splitter must be a designated ADSL microfilter/ phone jack splitter.

•ADSL Microfilter with Built-In Splitter. Use an ADSL microfilter with built-in splitter when there is a single wall outlet which must provide connectivity for both the wireless firewall and the telephone equipment.
