To someone that know about it.
I have a FTP Server (FileZilla) running over Win2003 with a Zyxel-700 router and i have a SDSL connection.
The NAT in the router is ok, ports from 20 to 25 are open. And ports from 1024 to 3380 are also open and all of those ports just said are pointing to Server IP.
I have made some tests and from inside of my network the FTP works well. I can see the directory and download the files.
Every time a external pc try to reach my FTP directory even via I.E. i instantly see in my ftp window messagens say that the user logged some times the one is able to see the list directory some times it doesnt. And a messagem appears to me.
425 Cant open data connection.
I got in touch with my ISP to make sure they dont block this kind of service as it is common, but i was told that, as we have a sDSL service running and also ISDN lines, no restriction is imposed from then.
So i would be glad to hear from someone, more experienced than me, a word that could resolve this problem.
Thanks in advance guys,
D. Furniel
