Like most people we’re keenly testing the pre RTM releases of Windows 8 and evaluating new hardware from HP to workout what we’d like to use for staff and students next year. Currently I have Windows 8 CP on a HP Folio13 and really like how it’s working for me. The only problem has been getting the Sonicwall SSLVPN client to work on Windows 8, which for the last week has stopped me from ditching my 2740p tablet and making the Folio13 my sole mobile device

After a few attempts at the NetExtender install it completed successfully after I installed *all* the drivers for the Folio13 from the HP site.

That got me excited and I thought I was all set, I tested the SSLVPN client and it authenticated and connected and looked like it was working. It wasn’t until later that evening when I went to use the VPN that I realised it wasn’t working at all, and even though the connection looked fine there was no network traffic being received by the VPN client.

A little digging this morning at the log and debug log files indicated an issue with the routes being added when connecting the vpn

By running route print I could see that the Sonicwall Netextender was interface 38

Open the Properties window for the NetExtender

Add the required routes to the bottom of the NxConnect.bat

route ADD 172.16.0.0 MASK 255.255.0.0 172.16.72.1 METRIC 5 IF 38
route ADD 172.16.1.3 MASK 255.255.255.255 172.16.72.1 METRIC 5 IF 38
route ADD 172.16.1.2 MASK 255.255.255.255 172.16.72.1 METRIC 5 IF 38

Funnily enough, you don’t seem to need the route delete commands in the NxDisconnect.bat?

route DELETE 172.16.0.0
route DELETE 172.16.1.3
route DELETE 172.16.1.2

And finally you need to change the privileges for NetExtender shortcut to run with administrator privileges. If you have the NetExtender as a startup program, go to

C:\Users\%username%\AppData\Roaming\Microsoft\Windows\Start Menu

Right-click on the shortcut and tick box for run this program as an administrator

After all of that my NetExtender settings seemed to be reliable and working the same as my Windows 7 devices
