Hi all, mwi1# uname -a FreeBSD mwi1.coffeenet.org 9.1-PRERELEASE FreeBSD 9.1-PRERELEASE #5 r239731: Mon Aug 27 09:53:18 CDT 2012 root@mwi1.coffeenet.org:/usr/obj/usr/src/sys/GENERIC amd64 My ipv6 connections hang for several seconds when this scrub rule is enabled: scrub all reassemble tcp no-df random-id This really agitates my browser and email client making them nearly useless at times. Disabling that rule makes ipv6 connections respond instantly as expected. Is this a known regression? My network interface is using the re(4) driver. Thanks!
