https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D242744 --- Comment #6 from Eugene Grosbein <eugen@freebsd.org> --- OTOH, RFC 2401 Appendix B https://tools.ietf.org/html/rfc2401#page-1-48 sta= tes that packets generated by IPSec transport mode must be allowed to fragment = over the path and this is incompatible with current behaviour keeping DF=3D1 for= TCP and may be an error in our IPSEC stack. Adding ae@ to CC: list. Andrey, what is your opinion on the problem? Should we clear DF bit unconditionally for outgoing IPv4 IPSec transport mode packets? --=20 You are receiving this mail because: You are the assignee for the bug.=
