Can't connect to FTP Server behind pfSense
related to the topic my problem is, that i can't connect to my ftp server. The server works pefectly when i'm connecting through the LAN IP, but I can't connect using the external IP and others also cannot connect. I'm not sure but i think there's a problem while I'm using a custom port.
My Setup contains the Router (192.168.0.1), a client (192.168.0.2) and a server (192.168.0.3). The server contains the ftpd (Port 7539).
I've done following things to get the server online:
- Port Forward to the command port and the data portrange
- Firewall rules are set for this ports to pass
- Outbound NAT everything is allowed
The site states showed me following entries:
tcp 192.168.0.1:80 <- 192.168.0.2:1446 FIN_WAIT_2:FIN_WAIT_2
tcp 192.168.0.1:80 <- 192.168.0.2:1447 TIME_WAIT:TIME_WAIT

udp [MYIPADDRESS]:54466 -> 220.127.116.11:53 MULTIPLE:MULTIPLE
Netstat -a on the client shows, that the client has sended a syn packet to the external IP:
TCP ***:1456 *******C.dip.t-dialin.net:7539 SYN_GESENDET
What's configured wrong that the router is showing CLOSED:SYN_SENT and nobody can connect to the server?!
As long as the client is configured properly for the custom port as well, shouldn't be a problem (doing the same thing on my setup). Are you sure you have the correct ports forwarded for passive mode as well? Is the ftp helper enabled?
