Troubleshooting the ISP Connection
If your VPN firewall is unable to access the Internet, you should first determine whether the VPN
firewall is able to obtain a WAN IP address from the ISP. Unless you have been assigned a static IP
address, your VPN firewall requests an IP address from the ISP. You can determine whether the
request was successful using the Web Management Interface.
To check the WAN IP address for a WAN interface:
1. Launch your browser and navigate to an external site such as www.netgear.com.
2. Access the Web Management Interface of the VPN firewall’s configuration at
https://192.168.1.1.
3. Select Network Configuration> WAN Settings from the menu. The WAN Settings screen
displays.
4. Click the Status button in the Action column of the WAN interface for which you want to
view the connection status. The Connection Status screen appears in a popup window. (For
more information, see “Viewing the WAN Port Connection Status” on page 9-21.)
5. Check that an IP address is shown for the WAN port.
If 0.0.0.0 is shown, your VPN firewall has not obtained an IP address from your ISP.
If your VPN firewall is unable to obtain an IP address from the ISP, you might need to force your
modem or router to recognize your new VPN firewall by performing the following procedure:
1. Turn off the power to the modem or router.
2. Turn off the power to your VPN firewall.
3. Wait 5 minutes, and then turn on the power to the modem or router.
4. When the modem’s or router’s LEDs indicate that it has reacquired synchronization with the
ISP, turn on the power to your VPN firewall.
If your VPN firewall is still unable to obtain an IP address from the ISP, the problem might be one
of the following:
• Your ISP might require a login program.
Ask your ISP whether they require PPP over Ethernet (PPPoE) or some other type of login.
• If your ISP requires a login, you might have incorrectly set the login name and password.
