[squid-users] hiding WAN IP from whatismyip.com ?

I was told that this is all I need to get this to work. I'm using
the latest version of squid 3.1.9 My browser proxy setting is set
 to localhost 3128 I also installed this proxy on
the same client machine I use to surf the web. I don't think it matters
Any advice is welcome.
