--- Comment #35 from John Nielsen <j...@jnielsen.net> --- I run a FreeBSD 14-STABLE router with vtnet under KVM on Arch Linux. 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 subnets (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. -- You are receiving this mail because: You are on the CC list for the bug.
