Limitations
The limitation of the client side due to ActiveX and Windows OS includes:
a.
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.
b.
Without Windows patch KB889527, ICMP (Ping) and PORT command of FTP cannot work in Windows XP
SP2.
c.
The forced termination (through CTRL+ALT+DEL or Task Manager) of the Internet Explorer will stop the
running of ActiveX. It causes IPSec tunnel can’t be cleared properly at client’s device. In this case, a reboot
of client’s device is needed to clear the IPSec tunnel.
d.
The crash of Windows Internet Explorer may cause the same result.
e.
There are some OS and browser which may not support Local VPN.

ICMP and Active Mode FTP
On Windows XP SP2 without patching by KB889527, it will drop ICMP packets from IPSec tunnel. This problem
can be fixed by upgrading patch KB889527. Before enabling IPSec VPN function on client device, please
access the patch from Microsoft’s web at http://support.microsoft.com/default.aspx?scid=kb;en-us;889527.
