hmmmmm, will do. I would hope that the NAT/firewall is simply repacking the
TCP segment into IP packets and would care what was inside... mind you, having
said that, if you are firewalling on TCP sockets etc, then I guess it does
need to open up and rebuild the segment??!!  good thinking Tim..

In theory it should help a little -- but I've never tried it.  Before
embarking, find out if your NAT/Firewall needs to support it also to take
advantage.  And let us know what you find out!

I am trying to resolve the age old problem of Terminal services users
accessing their home drives/profiles over high latency connections.

My client has multiple 40mbps connections and still suffers slow connection
problems..classic Long Fat Networks syndrome!

I am looking to implement RFC1323 (TCP extensions for High Performance),
which basically allows the TCP stack to negotiate a much larger receive
window size and thus radically improve their WAN TCP connections?

Have any of you networky spods out there have any experience with setting
the TCPOpt settings for RFC1323 in a terminal serivces environment?

Thanks in advance,

Brian
