ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308
Troubleshoot 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:
1. Laun
ch your browser and navigate to an external site such as www.netgear.com.
2. Acce
ss the web management interface of the VPN firewall’s configuration at
https://192.168.1.1.
3. Select Network
Configuration > WAN Settings > WAN Setup. The WAN Setup screen
for IPv4 displays.
4. T
ake one of the following actions:
- For IPv4. In th
e Action column, click the Status button of the WAN interface for which
you want to display the Connection Status pop-up screen (see Figure 13 o
n page 33).
- For IPv6.
In the upper right of the screen, select the IPv6 radio button. The WAN Setup
screen displays the IPv6 settings. In the Action column, click the Status button of the
WAN interface for which you want to display the Connection Status pop-up screen
(see Figure 30 o
n page 56).
5. Check t
hat an IP address is shown for the WAN port. If an IP address with zeros only is
shown, or if no IP address is shown, the VPN firewall has not obtained an IP address from
your ISP, or for IPv6, has not obtained or generated an IP address.
If your VPN firewall is unable to obtain an IP address from the ISP, you might need to
force your modem, dish, or router to recognize your new VPN firewall by performing
the following procedure:
1. T
urn off the power to the modem, dish, or router.
2. T
urn off the power to your VPN firewall.
3. W
ait 5 minutes, and then turn on the power to the modem, dish, or router.
4. Wh
en the LEDs of the modem, dish, or router indicate that synchronization with the ISP has
occurred, turn on the power to your VPN firewall.
If your VPN firewall is still unable to obtain an IP add
ress from the ISP, the problem might be
one of the following:
• Y
our ISP might require a login program.
For IPv4 connections, ask your ISP whether they require PPP over Ethernet
(PPPoE) or
some other type of login.
• For
IPv4 connections, if your ISP requires a login, you might have incorrectly set the login
name and password.
• For IPv4 co
nnections, your ISP might check for your computer’s host name. On a WAN
IPv4 ISP Settings screen, in the Account Name field, enter the host name, system name,
or account name that was assigned to you by your ISP. You might also have to enter the
