The protocol is FTP, what sort of proxy are you talking about here? I would like to have... ftp server <LAN> freebsd proxy <---Network Link---> freebsd proxy <LAN> Windows PC I assumed that my first step in this configuration is going to be getting the two freebsd boxes tuned and performing correctly.

Your propblem is similar to that encountered in sat links; where you have at least a 2 x 280ms RTT's and exteremely reliable/error free 'big' links (ok, that is not quite true; but the ECC is configurable so you simply set the error rate; and use power, width and dish size amongst other as a design parameter to play iwth). Another goed overview document is best current practices for satellite links (BCP28): http://www.faqs.org/rfcs/rfc2488.html or http://mmlab.snu.ac.kr/course/AdvancedInternet/reading/SatelliteTCP.htm Alternatively if a specific protocol is involved the use of a proxy for that protocol to intentionally break end to end semantics can do wonders. We've done this in the past for protocols such as ftp, http and smtp; and it works wonders.
