May I ask some help regarding configuration of Windows Server 2003 Passive FTP beyond (NAT/Firewall). My setup has only one public IP and the NAT/Firewall is enabled. DSL internet connection and port 21 is open in the firewall.
Internal network works fine but accessing the FTP outside also works only if you uncheck the "Use Passive FTP (for firewall and DSL modem compatibility)" option in the Internet Explorer.
Experts is there someting that I forgot to configure?
