Junos Pulse VPN client install issue – roll back

If you have many VPN clients (or network filters) installed on your system, Junos Pulse install may fail due to low maxfilters value in registry. Install hangs for some time and then rolls back.
If rollback is interrupted, or if install is triggered by web-installer it results is non-working VPN client with empty connection window.
This means that necessary services to run the clinet are missing – only UI files are installed.

To resolve the issue, you need to edit the Windows Registry key:
[code]HKLM/SYSTEM/CurrentControlSet/Control/Network/MaxNumFilters[/code]

This value defines the maximum number of network filter drivers allowed on the computer.

Try to change this value to 14 (maximum value), and the Junos Pulse install should finish successfully.

Cisco VPN client and 3G modems

Cisco VPN client is not working with 3G modems out of the box on Windows 7. The VPN will come up, but no traffic will pass throught the tunnel.
The release notes for Cisco VPN Client 5 state: The VPN Client on Windows 7 does not support WWAN devices (also called wireless data cards).

To fix the problem you will need to update your DNE component:

For 32-bit OS: ftp://files.citrix.com/dneupdate.msi
For 64-bit OS: ftp://files.citrix.com/dneupdate64.msi

After a restart VPN will work fine.
