The following reply was made to PR kern/106438; it has been noted by GNATS. From: Manuel Tobias Schiller <mala@hinterbergen.de> To: Remko Lodder <remko@elvandar.org> Cc: freebsd-gnats-submit@FreeBSD.org Subject: Re: kern/106438: ipfilter: keep state does not seem to allow replies in on spar64 (and maybe others) Date: Fri, 8 Dec 2006 09:38:33 +0100 --d6Gm4EdcadzBjdND Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Hello, I've gathered the information you have asked for, see the attachment. I hope it helps us to get an idea of what's going wrong. Any help with this would be appreciated. Thanks in advance. Manuel P.S. I did the | grep hme3 in the attachment to not clutter the output with irrelevant stuff. All other rules are bound to their respective interface (hme0, hme1, hme2, le0) and should not influence hme3. Besides, there's a lot of traffic going on on le0 which does not need to be mentioned in the ipfstat output because the machine in question is headless and can only be reached with a serial line (with a laptop down in the cellar) or a dedicated network interface (le0, for which I need to have rules that pass everything).
