Setting up proxy server on Mac

Hi All -

I have a new Powerbook, and I've successfully installed Cisco's VPN client.
I can browse the Oracle network fine, but can't browse web sites outside the
Oracle firewall.

On my PC, I could do this easily enough by enabling the proxy serve in IE
(www-proxy.us.oracle.com) on Port 80. When I set up the Oracle Network as a
Location in OS X.4, and configure Proxies in the same way, I can't get
outside the Oracle network in Safari.

Can anyone tell me how to do this?

Thanks,

Thomas
