Are you saying there are broken firewalls which strip TCP options in one direction only?It appears so.Ok, this is a possibility. And why it breaks is that if the ACK for the SYN+ACK comes back, the SYN+ACK sender can only assume that the window scale was accepted. Stephen, do you have a trace showing exactly this?
No, I don't have a br0ken firewall here. I can get out fine. When I setup with same kernel as packages.gentoo.org, it works fine as well.
