Thank you in advance. I haven't used KVM, so I hope there is no NAT involved between the two FreeBSD machines. Can you build a kernel with SCTP_DEBUG added to the options? Then use sudo sysctl -w net.inet.sctp.debug=3D1 to enable it on the server. This should provide some information what is = going on.
