Thanks for the replies. I finally managed to track down the issue, and it was scrub after all. I had "scrub all no-df reassemble tcp" and it was the "reassemble tcp" command that was causing the issue. I have now changed it to "scrub all no-df random-id". I had tested completely commenting out the scrub command earlier to no avail, but clearly wasn't thorough enough in killing states between tests. _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
