Hi Frank, The Win7 pc's are current on patches and the internal firewall is turned off. I've seen Stuarts response to the windows scaling. There are a lot of posts on Win7 about users turning off the TCP auto tune feature in win7. I may give that a try.

Hi Brandan, on the Windows 7 side all significant updates are done? You´ve checked the Windows 7 internal firewall, to be sure that the false is not pointed or placed in their? Because you wrote that the Win XP was not producing the problem, but Win 7 should do it, it is perhaps the TCP window scaling, as declared in the RFC 1323. In some similar other cases it was sometimes fixing the problem (pfsense) and in sometimes also not, but to quick test it out the spended time will to be of value. On the BSD side perhaps you try to turn of the scaling, I´m not an OpenBSD professional but it must be turn out by setting up a shell order likes <sysctl -w net.inet.tcp.rfc1323=0> If not or it must be typed in, in other direction it will be super that perhaps an OpenBSD familiar list member would correct this please. And at the other point I consider what Stuart Henderson was mentoring to you. Perhaps the best at all, but keeping an eye on the net6501 is also a nice option ;) I hope this is helping you out. ------------------------------------ Kind regards Frank -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Brandan Rowley Sent: Friday, December 09, 2011 11:11 PM To: '[email protected]' Subject: [Soekris] vr0 using OpenBSD stops responding. >Hi, >I am new to the list so be gentle if this has been posted already.
