2-8 Connecting the VPN Firewall to the Internet
v1.0, January 2010
• Select the DNS servers by selecting one of the following radio boxes:
– Get Automatically From ISP. Enables the VPN firewall to accept the DNS servers
that are dynamically assigned by the ISP. This is the default setting.
– Use These DNS Servers. Requires the VPN firewall to function with the static DNS
servers that were assigned by the ISP. Enter the IP addresses of the DNS servers in the
Primary DNS Server and Secondary DNS Server fields. A secondary DNS server is
optional.
6. Enter any modem-specific parameters to tune the VPN firewall for different modems:
• Serial Line Speed. Select the baud rate with which the serial port of the VPN firewall and
the modem connect. Available speeds range from 4.8Kbps to 460.8Kbps.
• Modem Type. If your modem type is listed in the pull-down menu, select it. For most
56Kbps modems, the U.S. Robotics 56K FAX EXT PnP selection should work. If this
does not work, select User Defined Modem and enter the initial string for your modem.
The initial string is usually defined in the modem’s user manual.
• Dial-up Type. Select one of the following options:
– Check the Tone radio box if your phone line supports touch tone dialing.
– Select the Pulse radio box for pulse mode dialing.
– Select the Other – use Dial String radio box to configure additional options such as
auto-answer. Consult your modem manual for dial strings.
7. Click Apply to save your settings.
As an optional step, set up the traffic meter for the dial-up connection (see “Configuring the
WAN Mode” on page 2-11).
Note: The response time of your serial port Internet connection will be slower than a
broadband Internet connection.
Tip: If you experience connectivity problems with the dial-up ISP, try a different
baud rate setting and ensure that the modem parameters you selected match the
modem connected to the VPN firewall.
