I think the fix is needed on your OpenBSD firewall, according to this:

David Miller: "Window scaling has been standardized and around for 14
years, RFC1323 was published in May of 1992. How much longer can we wait
or it to be deployed properly? :-)"

Window scaling is a good thing, because it improves speed on fast
connections to distant sites; the problem is that if an intermediate
node is buggy there are problems.
The same thing happened for ECN.

Best regards.
