I don't disable any checksums or do any other special configuration. I have NOT encountered this issue. The router uses IPFW and does NAT for several subne= ts (each of which is a different VLAN+bridge on the host and a distinct vtnet interface on the FreeBSD guest). That said if someone has specific failure cases or ways to reproduce I can help test. --=20 You are receiving this mail because: You are the assignee for the bug.=
