FTP NAT/Port Forwading
I have a pfsense box with two WAN, each provider have different router connected giving different IP segment. My problem is when I do a FTP from outside the network if fails to respond, and freezes at 150 Opening ASCII mode data connection for /bin/ls. This is my NAT rule
WAN TCP * * WAN address FTP_Ports 192.168.1.3 FTP_Ports
I also created a virtual server in the ISP router
Maybe a problem with your PASV mode settings? Typically FTP over NAT needs PASV mode with additional ports set up.
