[squid-users] Wccp/ transparent proxy/ gmail

We recently deployed a squid server with tproxy and wccp. I followed some of
the steps listed at
http://wiki.squid-cache.org/ConfigExamples/FullyTransparentWithTPROXY,
compiling tproxy support on iptables, squid, and recompiling the linux
kernel with tproxy support. We able to browse all sites with, but receive
timeouts after logging into gmail or hotmail. Yahoo mail seems to works.

Can anyone point me in the right direction, and tell me what I may be doing
wrong. BTW, we are using PIX for wccp, and have compiled ip_wccp.
