Цитата:
как сделать чтобы весь траф на сервер шел через прокси провайдера?
Средствами Serv-U точно никак.
Да и без провайдера это сделать вообще никак нельзя.
Next week is the scheduled release for Serv-U 7.0.
Some of the highlights are:
New web based user interface.
Support for HTTP, HTTPS, FTPS, and SFTP (via SSH2).
Support for multiple listeners / protocols per domain.
Bandwidth limitations for users, groups, domain, or the server.
Integrated web based client (Basic Web Client). An FTP client is no longer required to transfer files.
FTP Voyager JV, a full-featured, built-in Java client.
New, powerful FTP commands.
Major engine improvements including multi-threading to take advantage of today's multi-core computing technology.
