Miroslav Lachman <000.f...@quip.cz> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |000.f...@quip.cz --- Comment #3 from Miroslav Lachman <000.f...@quip.cz> --- I think I have related experience with csum vtnet bug. On one VM (in KVM) with 2 vtnet NICs IPsec VPN the packets are not going thru until I disabled csum on "LAN" NIC vtnet1: ifconfig_vtnet0="inet AA.BB.CC.DD netmask 255.255.255.128" ifconfig_vtnet1="inet WW.XX.YY.ZZ/24 -rxcsum -txcsum" This machine works like an IPsec gateway, vtnet0 is facing the internet, vtnet1 connects private network with clients connecting thru IPsec. Without -rxcsum -txcsum on vtnet1 the client machines cannot connect to anything in the outside world. First discovered with FreeBSD 12.3 (installed in the VM), later upgraded to 13.2. -- You are receiving this mail because: You are the assignee for the bug.
