As I feared, ip.id doesn't work in my case. My two captures are in
different networks, using a local client, and the remote server.  As
packets traverse these networks, the IDs seem to change. I guess
the equivalent of NAT is in play.

This also means the 'community-id' flow identified doesn't work
well for me, for similar reasons.

Is there a way I could share a pair of small captures with you?
(ten or so packets each); maybe there are some details within that
you may see I can use to associate these together.
