[squid-users] Squid doesn't work in WCCP, works fine as transparent

I have a squid 2.7 box, configured as transparent with wccp2 router
configured. ACL's are wide open for the whole 10.0.0.0/8 network. My WCCP2
router is a Cisco 6509 with a Sup32 running IOS.

The squid works fine if I add it in the browser on port 3128, but if I take
it out, internet stops unless I remove the wccp from the interface on the
router.

IP of Squid - 10.38.1.99
IP of router - 10.38.1.6
