Junos Pulse, Apple iOS, and Split-Tunneling

When you create (SSL)VPN access for you employees, you might enable split-tunneling to save corporate bandwidth. No split-tunneling means that all traffic is forwarded into the VPN tunnel. So if you browse the internet with an active VPN, the traffic goes through the VPN, and accesses the Internet through the corporate Internet connection. This isn't a big problem with a couple of employees, but with hundreds on the road or working from home, this might frustrate the employees in the building.

CiscoVPN Error 51 Annoyance

The CiscoVPN client (v4.9.01.0100) for Apple OSX throws an error every once in a while. Mainly when I just rebooted, or when I was forced to quit some hanging application (which also occurs on Macs). The error is:

Error 51: Unable to communicate with the VPN subsystem

Somehow, the VPN software looses contact with the network adapter (wired AND wireless). After this there are two things you can do;

  1. Reboot
  2. or restart the Cisco VPN Service manually.

The first is kinda obvious (it's almost a MS Windows strategy :)). The second one is done via the Terminal (Finder -> Applications -> Utilities -> Terminal). Just type the following command (followed by your password);

sudo /System/Library/StartupItems/CiscoVPN/CiscoVPN restart

The thing I don't understand is; Why hasn't Cisco incorporated this in the VPN client?

IF (Error 51 == TRUE)
DO CiscoVPN.restart

It seems that this 'bug' is present since the release of the Mac OSX version of the software.
