(OS X’s built-in VPN client also works, but it also logs me out of and cisco vpn error 51 then back into iChat every time I connect or disconnect from the VPN. The Cisco VPN Client doesn’t have this annoying problem, so I use it instead.) While the Cisco VPN Client works well most of the time, sometimes when I try to launch the application, I’m greeted with this error message in place of the usual connection dialog: Error 51: Unable to communicate with the VPN subsystem. Please make sure that you have at least one

network interface that is currently active and has an IP address and start this application again. The error is clearly incorrect, because my machine’s networking capabilities are otherwise fine—I can browse the net, send and receive e-mail, and connect to other machines in the house. I don’t get the error message all the time, and I don’t really know what causes it. It does seem to happen more often if I’ve slept and woke the machine, or moved it from one defined location to another, but even then, it’s not predictable. All I know for sure is that it’s annoying, because (until recently) the only fix I was aware of was to reboot the machine. One day, after probably the second or third time I’d restarted my machine, I decided there must be a better solution, so I went digging to see if anyone else had already found one—and they had. As detailed on the linked site, the solution is a relatively simple command that you execute in Terminal (found in Applications -> Utilities). After discussing the Terminal command with a friend, he came up with an even simpler version that works just as well: sudo SystemStarter restart CiscoVPN You’ll need to be an administrative user to run this command, and provide your admin password when asked. You won’t see any output from the command; the Terminal prompt will

Mac mini, Mac OS X (10.6.8) Posted on Jul 21, 2011 9:17 AM I have this question too by wickdillon,Solvedanswer wickdillon Level 1 (10 points) A: Check out this link: When going to a 64 bit OS (For me, it broke with Lion) the Cisco VPN no longer works because it is a 32 bit application. http://jmilbery.wordpress.com/2011/07/26/cisco-vpn-with-macos-lion/The native OS VPN works fine for error 5 me connecting to an ASA. Conencting to a VPN 3k concentrator can have mixed results, because they haven't updated those things in a while, and they will be end of support from Cisco next year.The OS VPN can be configured in your network properties, and you get to stay in 64 bit mode.

Someone suggested I hold down the 2 and 3 keys when I restart so that the system will revert back to 32 bit (whatever that means). It worked after I did that. I just need to remember to hold it down whenever I turn the computer on. Or else, I'll have to restart to access the VPN.I'm not sure what gets affected when you do this though. But, I seem to be able to carry on very well.
