Both worked perfectly under 4.5-STABLE from where I upgraded to 4.7-STABLE. The remote machine is an ``ibook'' (MacOS X), connected via modem to Internet, the ibook has not received any update whatsoever. It makes no difference whether ipfilter is compiled into the kernel or not. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
