Cisco vpn mac error 51

The built-in Cisco VPN client introduced in Mac OS X 10.6 Snow Leopard has the habit of disconnecting itself when re-keying should be performed but fails after about 48 minutes up to one hour. This timeout issue has been fixed in Mac OS X 10.6.4.

In versions of Mac OS X 10.6.0 up to 10.6.3, the problem can be worked around by increasing the re-keying period to e.g. 1 week.

The update to Snow Leopard 10.6.4 fixes the issue of the VPN disconnecting after 48 minutes many people have observed in 10.6.0–10.6.3. Therefore, there is no need to change the configuration of racoon anymore.

Note that this workaround severely decreases the security of your VPN connection as attackers now have up to 1 week to attack the phase 1 key.

I have no clue where Apple stores the configuration template for racoon, but I have found the following workaround.

Download cisco vpn mac os x client
  1. Create directory “/etc/racoon/remote” as root:

  1. Open a VPN connection to your Cisco VPN concentrator. This should result in the creation of a config file located at /var/run/racoon/10.1.1.1.conf, where 10.1.1.1 is the IP address of the VPN concentrator.

  2. Move this dynamically created file to /etc/racoon/remote before we change its contents:

  1. Now we edit the file, replacing all lines
  1. To make racoon read our converted file, insert a line
  1. Restart racoon:
