That is only related to 3.2. The 3.1 series has no Host: verification
security.

Requests made from the Squid server use the squid server IP as source.
They are useful only in eliminating ECN, PMTU, etc issues. They do not
test any problems with routing of TPROXY packets.
http://wiki.squid-cache.org/Features/Tproxy4 has quite a laundry list of
things to look at and be wary of. The troubleshooting section lists a
few ways packets can get lost or connections "hang". Anything marked
with a yellow asterisk icon, or a red cross icon may also be relevant to
this problem.

Which ones exactly? it may be something specifically related to them and
how squid is attempting to connect.
