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.

By recruiting someone with enough of a technology clue to scroll to the bottom of the message and read: "To unsubscribe from ...."

:P

David
p.s. and I wonder why I have so little faith in marketing and HR.
