MacOS – Connecting to VPN (Mac OS X)

macosvpnwindows

I'm trying to connect to VPN on Mac OS X via several ways:

Native vpn client (doing something like this:
https://www.publicvpn.com/support/MacOSX105.php)
By Anyconnect vpn client
By Cisco vpn client

In 3 case I receive the 51 error and I read, that it's ok for mac.
In 1 case I recieve no errors, just can't connect.
In case 2 I receive error message: "the vpn server did not respond", but ping to vpn server I try to connect is successfull.

What I'm doing wrong? When I tried to connect in Windows by cisco vpn client, connection was successfull. Can the problem be in that the vpn is based on windows?

The Cisco VPNClient app is not officially supported in 10.8. You may have some luck by using Java Preferences to specify the 32-bit JVM and either disabling the 64-bit or changing it to be secondary.

You're better off replicating the settings from your Cisco configuration into a new native VPN (IPSec) connection.

Look for the encrypted Group password in your .pcf file, then head over here to get the decrypted value. After that it should be fairly obvious.

How to share a Cisco VPN connection

I don't know if this option was also available in Snow Leopard, but if you are on Lion you could try the following:

Set up the native cisco client - if you don't know how, you can use this handy guide I created a few days back
Once you have tried and confirmed that everything works, your VPN connection should show up as one of the options in the Internet Sharing part of Preferences Sharing.
select the connection, choose on which network connection you'd like to share it and you're done.

Mac – VPN question on MAC

I found a thread on Apple's forums with similar issues to yours. [link]

Here's a solution that worked for one user although I allow myself the indulgence of finding his security practice rather terrifying.

I granted client certificate's private key access to all applications and > set always trust certificate in the Keychain Access. After that racoon successfully connected to vpn server. (there were about > 5 lines of errors in a log, but vpn worked) Next, I returned certificate's trust policy to system defaults. (private > key access reverted automatically). Now it works without errors.

I would rather recommend trying this method (next post from the source)

I used Keychain Access to modify the private key's trust policy. However, instead of setting it to all application, I just gave access to /usr/sbin/racoon.

Racoon is a process that is (also) used by OS X's VPN solutions.

This suggestion is based on the following lines:
