This is a multi-part message in MIME format. ------=_NextPart_000_0007_01BE8AAB.642A7F60 Content-Type: text/plain; charset="koi8-r" Content-Transfer-Encoding: quoted-printable Hello! I've used Windows ftp.exe from Microsoft. It works through NATD. According to FTP spec (RFC 959) daemon should make data connection to user-DTP, but it is impossible through NAT. Isn't it? It seems that client works according to FTP spec... I've logged outgoing (command) session using tcpdump. USER sergey PASS here is my pass word PORT 192,168,1,2,12,13 NLST PORT 192,168,1,2,12,14 NLST QUIT Can someone be nice enough to explain me details. Thanks, Sergey. ------=_NextPart_000_0007_01BE8AAB.642A7F60 Content-Type: text/html; charset="koi8-r" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META content=3D"text/html; charset=3Dkoi8-r" http-equiv=3DContent-Type> <META content=3D"MSHTML 5.00.2314.1000" name=3DGENERATOR> <STYLE></STYLE> </HEAD> <BODY bgColor=3D#ffffff> <DIV><FONT face=3DArial size=3D2>Hello!</FONT></DIV> <DIV> </DIV> <DIV><FONT face=3DArial size=3D2>I've used Windows <A=20 href=3D"ftp://ftp.exe">ftp.exe</A>; from Microsoft.
