    Sometimes your system may display error message 51 vpn snow leopard cisco. There can be several reasons for this problem.

    Apple Mac OS X users often encounter Cisco VPN client error 51: Unable to communicate with the VPN subsystem, as shown in the following screenshot:

    If this error persists, users will no longer be able to connect their VPNs to the Cisco VPN Client. It seems that Cisco VPN often gives owners an error “network” adapters disappearing and reappearing – a familiar scenario when the Ethernet cable TV is removed or reconnected to your wireless network.

    The solution provided will make the Cisco VPN continue to cope and reboot without issue.

    To fix most errors, close the VPN client, open a working terminal window (Applications -> Utilities -> Terminal) and enter one of the following commands:

    For older versions of the operating system:

    $ sudo Restart
    /system/library/startupitems/ciscovpn/ciscovpn For newer OS versions:
    $ sudo kextload /System/Library/Extensions/CiscoVPN.kext

    The previous commands require administrator rights, in fact the system will ask for a password for each administrator, as shown below:

    Another guide you can useUse with Cisco VPN subsystem reset, looks like this:

    If the problem with error 51 occurs again, just use the same method that worked for you before and you should be able to connect to the VPN. It may also be a good idea to create one small script containing all the commands so that it can be run every time an error occurs.

    On Windows 7, you will most likely need to use the Cisco IPsec client, which uses the same PCF approach as in XP. So I don’t know why you will have problems with Win7, if you still have problems with Win7 when using the Cisco IPsec client, you can start a new thread for this particular problem as it is different from Mac OS X and uses the built-in Mac client OS X.

    I haven’t heard of any issues with the built-in Mac X os client when properly configured and with the required b levels on the headendsecurity.

    Also, since this post has already been answered, it would be best to start a new thread to make sure you get the help someone needs.

    On the contrary, it didn’t work, and I rebooted the computer, the problem disappeared.

    Great: Works to solve the same issue when Windows crashes on a Mac (restarting the Cisco VPN service).

    He doesn’t have a task for me. I am getting this great error since I installed all cisco vpn. Property around version 4.9 as well. What else should I do?

    Yes, my last friend pointed this out to me, and I’ve been confirming it ever since. Apple’s new security system kills publishing to CiscoVPN when using dial-up adapters. I don’t have a workaround yet, I must have heard that this is an Apple problem, not Cisco. (I don’t neednothing to back it up.) I wish Cisco would just go upstairs and use the standard IPSec VPN that comes with OSX. It will probably make life a lot easier. Should I start a blog post if I add something to it.

    I still don’t have a wired or wireless connection. Even restarted for useful measure.

    Identify an issue with Cisco and OSX VPN technology that was resolved in the latest Apple software update. Apparently, a major software update last March broke the connectivity of the Cisco VPN software, although it didn’t fix the “error 51” that this website talks about. Connections will be established and a password will be requested, on the contrary, after sending, the connection should not be established, and finally Cisco, as the VPN application times out and returns to the “not connected” state. In May 2007, Apple released an update that does some technical work.service between Cisco VPN and thus OSX, so everything works as expected again.
