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 w= hich 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. --=20 You are receiving this mail because: You are the assignee for the bug.=
