AFAIR, 2.5 did support transparent proxying via IPFW, at least on
RELENG_4, without problems, but I must admit I never tried it on RELENG_5
and up :-/

Could you try rebuilding the port without kqueue support? Just a guess,
but you can never tell.

I suspected issues, that's why www/squid will stay at 2.5 for a while.
2.6.STABLE1 was released way to fast for my taste, RC3 would have been
better (I had prepared a port for RC2 for submission when I noticed the
STABLE1 announcement on squid-users :-/ .)

Please report all problems you encounter directly to the squid
developers, either via bugzilla or to the squid mailinglists; my
skillset limits me to stuff like checking for compilation and packaging
errors... The squid folks seem to be using mostly linux, Solaris, and
Windows nowadays, so they are probably not aware of our FreeBSD specific

You're welcome! I am sorry that I cannot help you much myself regarding
the abovementioned issues. I run 2.6.RC2 in a very lightly loaded
environment without issues as of now.

Best regards,
