Common Problems and Solutions
1. I’m having trouble getting my VPN tunnel to connect. What should I do?
Perform the following steps until the VPN tunnel connects:
A. Double-check all of the settings. Make sure the IPSec Setup settings of the 10/100 16-Port VPN Router
match the IPSec Setup settings of the remote VPN router or client, including the Preshared Key and
Phase1 and Phase2 SA Life Time settings, which are used in the IKE with Preshared Key mode.
B. Click the
Log
tab of the Router’s Web-based Utility. Click the
View System Log
button. From the drop-
down menu, select the
VPN Log
. The error message will indicate which setting is incorrect and needs to
be changed on either the 10/100 16-Port VPN Router or the remote VPN router or client.
C. Make sure the IP address of the Remote Secure Gateway or Client is correct. Click the
System
Management
tab of the Router’s Web-based Utility. Select the
Ping
radio button. Enter the IP address of
the Remote Secure Gateway or Client in the
Ping host or IP address
field. Then click the
Go
button.
2. My VPN tunnel connects properly, but it frequently drops the connection. What should I do?
Through the Router’s Web-based Utility, access the settings for your VPN tunnel. In the IPSec Setup section
with IKE with Preshared Key mode selected, increase the Phase2 SA Life Time setting to
28800
seconds,
which is eight hours. Then increase the Phase2 SA Life Time setting to
28800
seconds on the remote VPN
router or client. If you need to check the status of your VPN tunnel, view the
VPN Summary
screen of the
Router’s Web-based Utility.
3. I’m trying to access the Router’s Web-based Utility, but I do not see the login screen. Instead, I see a
screen saying, “404 Forbidden.”
If you are using Windows Explorer, perform the following steps until you see the Web-based Utility’s login
screen (Netscape Navigator will require similar steps):
1. Click
File
. Make sure
Work Offline
is NOT checked.
2. Press
CTRL + F5
. This is a hard refresh, which will force Windows Explorer to load new webpages,
not cached ones.
3. Click
Tools
. Click
Internet Options
. Click the
Security
tab. Click the
Default level
button. Make sure
the security level is Medium or lower. Then click the
OK
button.
