SmartTunnel doesn't work in Mac. I have tried with any version of Macintosh and any web browser. The version of the ASA-5540 is 8.2. I know there is a bug about configure the smart tunnel with the IP address of the server instead of the name. Nothing new happens. When I try to open the tunnel, I download the tunnel_mac.jnlp file and it ask me for trust the certificate. After doing this, the tunnel is not open.
I have this problem too.
