there _was_ a bug in the Cisco PIX whereby it cleared TCP window-scaling

this can be tracked through cisco bug-id CSCdy29514.
this was fixed back in August 2002 with the fix incorporated into PIX
software releases 6.1.5 and 6.2.3 and later.
any 'recent' (i.e. last 2.5 years) releases don't have this problem.
(or, at least, we don't think so..).
I have identified two firewalls with this problem and both of then are
running PIX software version 6.3.4 - I have not yet managed to
persuade there respective admins to update to 7.0.1 (or 6.3.4.115) -
so until then I am just turning window-scaling off.
If you have a Cisco contract, you need to make sure that your account
manager will allow the upgrades.
But as I said before, this was fixed long time ago.
I hope you can upgrade soon.
