Under normal conditions, the Virtual Private Network (VPN) client
works in harmony with your operating system, your network connection with
your Internet Service Provider (ISP),
and any networking or communication-related software or hardware
that you have in order to create a VPN connection. Due to the many
variations of ISPs and communication-related programs and hardware
devices, there are situations where the VPN client will not work properly.
The following is a list of known issues with the VPN client.
(NOTE: This page was updated on June 12, 2008 to give any known
issues with the VPN 3000 client for Windows and Mac OS X. Any Windows or OS X
users who still have the VPN 5000 client should uninstall the VPN 5000
software; they should then download and install the VPN 3000 software.)

Wireless access point or router
|
When the VPN client is activated, it receives an IP address that
begins with 128.8 (a UMCP IP address) but it cannot access any UMCP or
non-UMCP websites.
|
The wireless access point or router may be blocking part of
the VPN tunnel. Try the following possible remedies:
- Upgrade the firmware for your wireless access point or
router (firmware is the term for the software that operates your wireless
access point / router). Visit vendor's website of your
wireless access point or router and find the firmware for the exact make
and model of your networking hardware; then, download and install it.
- If updating the firmware did
not work, try opening the following ports in your router in order to
allow network
traffic to travel over that port in both directions over TCP (you will
need to consult your router manual on how to do this):
- TCP port 10000
- TCP port 1723
- UDP port 500

The VPN 3000 client either will not install or will not
work properly due to the presence of a different VPN
program on the same computer.

Uninstall the other VPN software. There is no support for using
other VPN software.

Open and connect the VPN profile of your choosing before opening
any Internet-required applications.
