Well, I have seen things like this happen when supposedly "smart"
security devices are placed in line. I had a experience with a large
company that used Cisco IPS sensors. By default the IPS sensors tried
to "fix" problems with changing TTLs in the middle of a stream or
packets showing up out of order. Even when a host sets the do not
fragment but the MTU has to be set smaller to fit down a VPN, so
things get fragmented... there are many reasons why some of these
"problems" are generated, when they are not actually problems. The
unlogged "fixes" the IPS sensors made on the traffic just made it
worse. The traffic captures looked something like your example.
I am not saying that is definitely the problem. You know the network
between the two sites better than I do. Maybe there are some
conflicting things going on.
What does mtr (Matt's Traceroute) show from one host to the other ?

Can someone take a look at that tethereal output and tell me what
they think? Is that a seriously screwed up net connection or is that normal?
That is downloading a file from our website in San Diego to our New
York office taken on the New York firewall box
I am trying to diagnose why we continually have dropped packets and
problems with the VOIP audio quality. I can't figure out if it is us
or our network provider.
