It is very simple. We have one machine "A" with outgoing interface (vtnet0) and
some virtual (like ipsec0 or tun0).

We also have another VM "B" in the same network and also vtnet0 interface which
has nginx serving FreeBSD ISO file.:)

If we directly request the ISO file from "A" works alight.

If we request the file via VPN interfaces, we get a lot of retransmissions
because packets began to be discarded.

I'm attaching the dump file, captured on vtnet0.
