Isn't port 407 privileged and port 1419 not?


Yes, but I don't think this plays a roll. It turns out we're sending two
datagrams in quick succession from the same source port, one to 1419 and one
to 407. The one to 1419 makes it and the one to 407 doesn't. The new clue
is that if I reverse the order, the one to 407 makes it and the one to 1419
doesn't. In other words, the first one gets there and the second one
doesn't. BTW, this works fine when the same two machines are on an Ethernet
together instead of connected by VPN.

My new hypothesis is that something along the way is dropping the second
packet because it follows the first one too quickly. So I have a new
experiment to run....

Do you have a firewall engaged? I'm not sure it matters, but that can sometimes cause funky behavior.

Regards,

Justin
