ProSafe Wireless-N 8-Port Gigabit VPN Firewall FVS318N
Note:
If your ISP assigns a private WAN IP address such as 192.168.x.x
or 10.x.x.x, the DDNS service does not work because private
addresses are not routed on the Internet.
To configure DDNS:
1.
Select
Network Configuration > Dynamic DNS
. The Dynamic DNS screen displays
(see the following figure).
2.
Click the submenu tab for your DDNS service provider:
Dynamic DNS
for DynDNS.org (which is shown in the following figure)
DNS TZO
for TZO.com
DNS Oray
for Oray.net
3322 DDNS
for 3322.org
Figure 25.
3.
Click the
Information
option arrow in the upper right of a DNS screen for registration
information (for example, DynDNS Information).

Access the website of the DDNS service provider, and register for an account (for example,
for DynDNS.org, go to
).

Configure Advanced WAN Options and Other Tasks
The advanced options include configuring the maximum transmission unit (MTU) size, port
speed, wireless VPN firewall’s MAC address, and setting a rate limit on the traffic that is
being forwarded by the wireless VPN firewall.
Note:
Although you can access the Broadband Advanced Options screen
only through the Broadband ISP Settings (IPv4) screen, the
advanced options apply to both IPv4 and IPv6 WAN connections.
To configure advanced WAN options:
1.
Select
Network Configuration > WAN Settings > Broadband ISP Settings
. The
Broadband ISP Settings screen displays the IPv4 settings (see
Figure 10

screen depend on the DDNS service provider that you have selected. Enter the following
settings:
Host and Domain Name
The host and domain name for the DDNS service.
Username or

Use wildcards
If your DDNS provider allows the use of wildcards in resolving
your URL, you can select the
Use wildcards
check box to
activate this feature. For example, the wildcard feature
causes *.yourhost.dyndns.org to be aliased to the same IP
address as yourhost.dyndns.org.
Update every 30 days
If your WAN IP address does not change often, you might
need to force a periodic update to the DDNS service to
prevent your account from expiring. If the
Update every 30
days
check box displays, select it to enable a periodic
update.

MTU Size
Make one of the following selections:
Default
Select the
Default
radio button for the normal maximum transmit unit (MTU)
value. For most Ethernet networks this value is 1500 bytes, or 1492 bytes for
PPPoE connections.
Custom
Select the
Custom
radio button, and enter an MTU value in the Bytes field. For
some ISPs, you might need to reduce the MTU. This is rarely required, and
should not be done unless you are sure it is necessary for your ISP connection.

Speed
In most cases, the wireless VPN firewall can automatically determine the connection speed of the WAN
port of the device (modem, dish, or router) that provides the WAN connection. If you cannot establish an
Internet connection, you might need to manually select the port speed. If you know the Ethernet port speed
of the modem, dish, or router, select it from the drop-down list. Use the half-duplex settings only if the
full-duplex settings do not function correctly.
Select one of the following speeds from the drop-down list:
AutoSense
. Speed autosensing. This is the default setting, which can sense all Ethernet speeds and
duplex modes, including 1000BASE-T speed at full duplex.
10BaseT Half_Duplex
. Ethernet speed at half duplex.
10BaseT Full_Duplex
. Ethernet speed at full duplex.
100BaseT Half_Duplex
. Fast Ethernet speed at half duplex.
100BaseT Full_Duplex
. Fast Ethernet speed at full duplex.
1000BaseT Half_Duplex
. Gigabit Ethernet speed at half duplex.
1000BaseT Full_Duplex
. Gigabit Ethernet speed at full duplex.
Router’s MAC Address
Each computer or router on your network has a unique 48-bit local Ethernet address. This is also referred to
as the computer’s Media Access Control (MAC) address. The default is set to Use Default Address.
Make one of the following selections:
Use Default Address
Each computer or router on your network has a unique 32-bit local Ethernet
address. This is also referred to as the computer’s Media Access Control (MAC)
address. To use the wireless VPN firewall’s own MAC address, select the
Use
Default Address
radio button.
Use this computer’s MAC
Address
Select the
Use this computer’s MAC Address
radio button to allow the
wireless VPN firewall to use the MAC address of the computer you are now
using to access the web management interface. This setting is useful if your ISP
requires MAC authentication.
Use this MAC Address
Select the
Use this MAC Address
radio button, and manually enter the MAC
address in the field next to the radio button. You would typically enter the MAC
address that your ISP is requiring for MAC authentication.
Note:
The format for the MAC address is 01:23:45:67:89:AB (numbers
0–9 and either uppercase or lowercase letters A–F). If you enter a MAC
address, the existing entry is overwritten.

Additional WAN-Related Configuration Tasks
If you want the ability to manage the wireless VPN firewall remotely, enable remote
management (see
Configure Remote Management Access
on page 322). If you enable
remote management, NETGEAR strongly recommends that you change your password
(see
Change Passwords and Administrator and Guest Settings
on page 320).
You can set up the traffic meter for the WAN interface, if you wish. See
Enable the WAN
Traffic Meter
on page 335.
Verify the Connection
Test the wireless VPN firewall before deploying it in a live production environment. Verify that
network traffic can pass through the wireless VPN firewall:
Ping an Internet URL.
Ping the IP address of a device on either side of the wireless VPN firewall.
What to Do Next
You have completed setting up the WAN connection for the wireless VPN firewall. The
following chapters and sections describe important tasks that you need to address before you
deploy the wireless VPN firewall in your network:
Chapter 3, LAN Configuration
Chapter 4, Wireless Configuration and Security
Configure Authentication Domains, Groups, and Users
Manage Digital Certificates for VPN Connections
Use the IPSec VPN Wizard for Client and Gateway Configurations
Virtual Private Networking Using SSL Connections
