That either means that AT&T is doing something very clever, or I
don't understand what's going on. Or both.
Ok, next part. Reset your network settings.
Check your IPv6 "readiness" by visiting  and performing appropriate
link clicks according to .
Oh, and the file - /tmp/fastly.pcap . I'm still interested in it.
The missing file is attached.
The contents are different from what I hoped for. Two TCP IPv4 packets,
and that's it. Does not clarify things at all.
I went to URL #1 and ran their compatibility test. The result was:

Translating from AT&T lingua that's probably means that you should not
have IPv6, or that /60 block they assigned to you does not function.
Or not. I suggest you to clear it with them.
However, when I logged in to my router it showed the Broadband configured
rot all ports 1 through 4 and being 'Auto', and IPv6 is shown as 'On' for
IPv6, DHCPv6 and DHPv6 Prefix Delegation and with the Router Advertisement
MTU WITH A VALUE OF 1500.
That's unusual. For IPv6 it should be 1480 if they are still using
tunnel. But it does not explain traceroute problem (a typical traceroute
packet size is much smaller).
I need to think about it. I have that feeling that I'm missing something
I will appreciate your further thoughts.
Frankly, I don't have much confidence as far as AT&T being of any help.
The installer that Upgraded us to a fiber optic network was quite
knowledgeable, but had played with Linux a bit in the past but got
