I am having problems with a remote-access VPN configuration that uses long PSKs. If I use a short PSK, like for instance "cisco", everything is fine but if I use longer stuff (some 20+ chars) I get an error when I try to connect with the VPN client (the error indicates a wrong PSK).

I am worried that using a very short (10 chars?) PSK isn't optimal for security.

Thank you very much for the input.

Although apparently, my problems were due to an outdated Cisco VPN Client software. The latest version fixed this issue.

Be aware maximum length of VPN3000 concentrators is 32 characters.
