Can't connect to FTP Server behind pfSense

irgendwer

Hey there,
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
tcp 192.168.0.1:80 <- 192.168.0.2:1448 FIN_WAIT_2:FIN_WAIT_2
tcp 192.168.0.1:80 <- 192.168.0.2:1451 TIME_WAIT:TIME_WAIT
tcp 192.168.0.1:80 <- 192.168.0.2:1453 ESTABLISHED:ESTABLISHED
tcp [MYIPADDRESS]:7539 <- 192.168.0.2:1450 CLOSED:SYN_SENT
udp 192.168.0.1:53 <- 192.168.0.2:1034 SINGLE:MULTIPLE
udp 192.168.0.1:53 <- 192.168.0.3:32771 MULTIPLE:MULTIPLE
udp [MYIPADDRESS]:62417 -> 85.25.5.69:123 MULTIPLE:SINGLE
udp [MYIPADDRESS]:54466 -> 217.237.148.70:53 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?
