Windows Internet Explorer: From the Tools menu, click on Internet Options. Select the
Programs tab and click Manage add-ons button to enter the Manage add-ons dialogue box,
where you can see VPNClient.ipsec is enabled.
During the first-time login to AMG-2001 with Local VPN, Internet Explorer will ask clients to
download an ActiveX component of IPSec VPN. Once this ActiveX component is downloaded, it will
run in parallel with the "Login Success Page" after the page being brought up successfully. The
ActiveX component helps set up individual IPSec VPN tunnels between clients and AMG-2001 and
check the validity of IPSec VPN tunnels between them. If the connection is down, the ActiveX
component will detect the broken link and decompose the IPSec tunnel. Once the IPSec VPN tunnel
was built, all sent packets will be encrypted. Without connecting to the original IPSec VPN tunnel, a
client has no alternative way to gain network connection beyond this. IPSec VPN feature supported
by AMG-2001 directly solves possible data security leak problem between clients and the system via
either wireless or wired connections without extra hardware or client software installed.
• Limitations
The limitation on the client side due to ActiveX and Windows OS includes:
Internet Connection Firewall of Windows XP or Windows XP SP1 is not compatible with IPSec
protocol. It shall be turned off to allow IPSec packets to pass through.
Without patch, ICMP (Ping) and PORT command of FTP can not work in Windows XP SP2.
The forced termination (through CTRL+ALT+DEL, Task Manager) of the Internet Explorer will
stop the running of ActiveX. It causes that IPSec tunnel cannot be cleared properly at client
device. A reboot of client device is needed to clear the IPSec tunnel.
The crash of Windows Internet Explorer may cause the same result.
Internet Connection Firewall
•
In Windows XP and Windows XP SP1, the Internet Connection Firewall is not compatible with IPSec.
Internet Connection Firewall will drop packets from tunneling of IPSec VPN. Please TURN OFF
Internet Connection Firewall feature or upgrade the Windows OS into Windows XP SP2.
