ON client computers I receive this error when trying to acces any FTP site. > ISA Server: extended error message : > 200 Type set to A. > 502 Illegal PORT Command ISA server it have a VPN to a satelite provider. I was adviced to setup my BROWSER CLIENT TO work in PASIVE MODE. Not all IE have options of PASIVE mode under INTERNET OPTIONS / ADVANCED / BROWSING ... so I search some dedicated FTP client. I found many but only few it have options to work TROUGHT A PROXY SERVER. Question: since ISA PORT it is 8080 what port should I setup to FTP CLIENT ? if I setup 8080 it do not work, I setup PASIVE mode - do not work, I setup port 21 - do not work. Any advice will be appreciated as soon as posible. Bogdan
