1. DNS lookups fail completely. 204.127.198.4 is among a handful of
external DNS servers I use, whether defined as dns_nameservers in
squid.conf or picked by squid automatically from /etc/resolv.conf:

Is IPv6 dual-stack enabled in your OS? it looks like the v6 sockets are
unable to do the v4-mapping they need to handle v4 traffic.
I find it a bit weird that setting TOS also fails, its one of the older
functionality and shared between both IP protocols.
I'd think so. I'm using 6to4, if that matters. Here's the snippet from
config.log:t

Here's cache.log with debug_options 0,5 78,9:

Hmmm, this is looking suspiciously like a problem we just hit on OpenBSD
as well, due to hybrid v4-mapping not being available. Squid does not
detect it very well.
Since we have a good tester who knows the fine details to look for
there. I'll fix that first then see if the same works for you.
