NAT CHECKSUM RST problem on 5.1.8 r111374 (Qt5.5.1)

Hello. I have just installed FreeBSD 11.0-RELEASE-p1 [1] on VirtualBox Version 5.1.8 r111374 (Qt5.5.1) macOS 10.12.1. I have noticed problems when NAT is active - I get "connection reset by peer" quite often. This does not happen on Bridge interface. Using TCPDUMP I have noticed incorrect checksum on packet going out, just before I get RST from remote.

To reproduce:

  1. Install FreeBSD 11.0-RELEASE-p1 VM using NAT.
  2. Login as root.
  3. Make sure network is working (ping, DNS).
  4. Type pkg to bootstrap packaging system - it will fail.
  5. Try to fetch some packages from [2] - it will fail for some packages.
