Using Hushmail With PureVPN Securely?

Hello:

If you log into hushmail using one of the settings of purevpn, hushmail will see your real home I.P. address and not the I.P. address of purevpn.com, but if you log into hushmail using cryptohippie then your real home I.P. does not show up on the location page that hushmail has on you, but the cryptohippie I.P. shows up on the location page of the user.

But when I use whatismyipaddress.com with those settings I am using on purevpn.com the I.P. of purevpn only shows up. Hushmail must have some sophisticated technology that penetrates your true I.P. I wonder what they are using?

Can you tell me what settings I need to use when I use purevpn.com so that my home I.P. does not show up when I log into hushmail.com but only the I.P. of purevpn.com shows up?

Thanks, Dave
