[OpenAFS] Networking AFS related problem

[Harald Barth]

Yes, the first packets are quite small until you start to actually
transfer chunks of files.

If you don't see any traffic coming back then something is
blocking.... On the server (the VLDB server(s) would be the first ones
to be contacted as you see) you can see if outgoing or incoming is
blocked.

If NAT is involved, i can be broken NAT as well.

I guess your IP provider lives in the IT world of 2022 where "Internet
service" consists of mostly TCP/HTTPS and definitely not UDP ;-)
