[squid-users] TPROXY Issues

I am back trying to solve my tproxy issues.

Running Ubuntu server with Kernel 2.6.28-11-server, iptables v1.4.3.1,
squid 3.1.0.6

I am able to browse transparently but proxy test sites still detect the
cache.

http://www.whatismyip.com says the following

Your IP Address Is 66.78.98.25
Other IPs Detected: 66.78.102.2
Possible Proxy Detected: 1.1 cache-01.ripnet.com (squid/3.1.0.6)

Why is this site detecting my proxy??
