https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=290773 --- Comment #1 from Michael Tuexen <tuexen@freebsd.org> --- (In reply to lg from comment #0) A couple of clarification questions: * For reproducing the issue you copy a file from the VM to some other host? * Is the other host another VM running in parallel to the FreeBSD VM? * Is the other host a physical host? * Are you running any sort of NAT/Firewall on the FreeBSD VM? * Could you provide the output of ifconfig vtnet0? * Could you provide the output of sysctl hw.vtnet * Could you provide the output of sysctl dev.vtnet.0 * Could you run tcpdump -i vtnet0 -w out.pcap and share the .pcap file (a couple of seconds should be enough). -- You are receiving this mail because: You are the assignee for the bug.
