Cisco's VPNClient on Mac OSX, you might be familiar with (or tormented by) "Error 51: Unable to cisco vpn error 51 mac lion communicate with the VPN subsystem". The simple fix is to quit VPNClient, open a Terminal window, (Applications -> Utilities -> Terminal) and type one of the following: (for
Cisco Vpn Client Mac Error 51 Unable Communicate Vpn Subsystem
older versions) sudo /System/Library/StartupItems/CiscoVPN/CiscoVPN restart (for newer versions) sudo kextload /System/Library/Extensions/CiscoVPN.kext and give your password when it asks. This will stop and start the "VPN Subsystem", or in other words restart the CiscoVPN.kext extension. Cisco seems to have problems when network adapters disappear and reappear, something that happens commonly in Wireless or Dial-up scenerios. Sometimes putting a cisco vpn mac osx system to sleep, disconnecting an Ethernet cable or simply reconnecting your wireless will cause CiscoVPN to loose track of the network adapters on the system. Considering that CiscoVPN is typically used by telecommuters, this is an astonishing oversight on Cisco's part. The above hack should side-step all of these issues by causing the CiscoVPN to re-initialize. It makes one ask, why couldn't Cisco have just put the restart into their client? Or a better idea would be to not reinvent the wheel and use the existing IPSec VPN support in OSX! Am I missing something? EDIT: The MacWorld guys came up with a simpler way to do the same thing: sudo SystemStarter restart CiscoVPN Posted by Anders Brownworth Monday, November 13, 2006 7:25 PM Tweet Comments (269) Jeff from Chicago #1 | Friday, March 23, 2007 6:53 AM Thanks for the tip - this worked like a charm. todd from boston #2 | Thursday, March 29, 2007 10:29 AM you the man - thanks!

In my experience, almost every operating cisco vpn error system upgrade has needed a update to the VPN client software. Have you checked if there's a newer Cisco client for your office?That said, have you tried uninstalling and reinstalling the Cisco software? Also, OSX's built-in VPN client works for many Cisco implementations, so works for a lot of people. If possible, I recommend uninstalling Cisco's software an see if you can configure OSX's VPN. I'm currently using OSX's VPN to a Cisco ASA 5510 with SecureID authentication. With OSX 10.6.8 and 10.7.

on 6/30 News archive rss BOL Webmail Have a question? Click here to search our knowledge base. © Bruin OnLine 7/22/2011: Cisco VPN Client compatibility with Mac OS 10.7/Lion The current version of the Cisco VPN Client does not appear to run properly if Mac OS is running the 64-bit kernel. Mac OS 10.7/Lion runs the 64-bit kernel by default. Users will see the error "Error 51: Unable to communicate with the VPN subsystem" when starting the VPN. Until Cisco releases a compatible client, there are a few workarounds available: Set Mac OS X to boot using the 32-bit kernel according to the instructions in Apple's support article Configure the Mac OS X built-in VPN client to connect to the UCLA VPN using any one of the following protocols: PPTP Cisco IPSEC Please note that this issue is not specific to Mac OS 10.7/Lion. Apple has a list of Macs that use the 64-bit kernel by default as well as instructions to find out if you're using 64-bit mode.
