On my office windows XP laptop I use a program called Bitvise Tunnelier to establish ssh tunnel to a in-house MySQL database. In the Tunnelier program I also need to provide address of corporate http proxy server in order to establish tunnel.

On my personal mac laptop, I use Cisco Anywhere client to establish a VPN connection to my corporate network. But i'm unable to establish ssh tunnel to mysql database using ssh. How do I specify the proxy server address in the ssh command?

As additional info when i'm using office laptop (whether in home or office) I can successfully ping to the server address specified in the Tunnelier program. But i cannot ping the same server using my mac machine (even after connecting via VPN).

So basically i'm unable to understand what's going on and what steps i can take to debug this problem .
