In my experience, almost every operating 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 Mac OS X Posted October 10th, 2008 by John Bickar in Mac OS X SIG Answer mac vpn When using https://techcommons.stanford.edu/topics/mac-os-x-sig/troubleshooting-cisco-vpn-client-mac-os-x the Cisco VPN Client from off-campus, sometimes it will throw an error on launch and prevent you from connecting to the VPN concentrator. (The specific error is "Error 51: http://apple.stackexchange.com/questions/17823/how-can-i-make-the-cisco-vpn-client-work-with-lion Unable to communicate with the VPN subsystem.") Usually, you can fix this by opening up Terminal and entering the following command at the command prompt (followed by hitting "Enter"): vpn client sudo /System/Library/StartupItems/CiscoVPN/CiscoVPN restart However, if you run into Error 51 on the first launch of VPNClient, you'll get the following error: sudo: /System/Library/StartupItems/CiscoVPN/CiscoVPN: command not found In this case, deleting VPNClient from /Applications and reinstalling the latest version should fix the problem. (A reboot also might do the trick.) Another error that vpn client mac you may encounter is "Error 5: No hostname exists for this connection entry. Unable to make VPN connection." In this case, right-click the Stanford_Public_VPN connection entry in the connection window and choose Modify from the contextual menu. In the host field, enter su-vpn.stanford.edu and click Save. (Uninstalling and reinstalling also should fix this problem.) Using OS X's built-in VPN vs. Cisco client Submitted on May 27th, 2011 by mallis The instructions for connecting via VPN suggest downloading the Cisco VPN client. If OSX is running in 64-bit mode (mine is) the Cisco client will not work at all. I followed the instructions here: http://anders.com/guides/native-cisco-vpn-on-mac-os-x to add a VPN connection using OS X's built-in Cisco VPN functions. It was easy, and better than adding another kernel extension to the mix, especially one originally designed to run under OS X 10.4/ The information gathered on these pages is generated by the Stanford University community with significant support fromthe Academic Technology Specialist Program, SULAIR Information Center, SU Webmasters, Stanford Video and Multimedia Group and IT

Have you tried just entering your VPN settings into the Lion VPN software - many times you don't even need the cisco client software. –bmike♦ Jul 20 '11 at 16:25 1 Cisco "AnyConnect VPN Client" works just fine with LION. I guess you mean the literal, Cisco "VPNClient"? –user8306 Jul 25 '11 at 0:14 Carl - Have any of these answers helped you? Have you gotten an updated software from Cisco that addressed the issue in the mean time? –bmike♦ Aug 9 '11 at 20:37 If (like me) you can not obtain Cisco AnyConnect VPN Client from Cisco, you could try a third party alternative. Shimo works for me. –Graham Perrin Aug 16 '11 at 17:46 add a comment| 3 Answers 3 active oldest votes up vote 15 down vote Have you tried using the on-board Cisco VPN Client? I had serious issues with Cisco's client (it kept kernel panik-ing my Mac) and had the IT department help me set up the built in client. It basically works the same way as it does on an iPhone or iPad, so if you can connect with that device, you should be able to do so as well with your Mac.
