since the change from two single WAN internet connections to uplink balancing we have problems to connect to our FTP server in passive mode.
Old setup:
- 2 WAN Connections
- 2 Firewall rules: Any => ftp & ftp passive => ftp server
- 2 DNAT entries:
Traffic selector: Any → FTP → External internet (Address)
Destination translation: ftp server → FTP
Worked like a charm [:D]
Our new setup:
Firewall rules and DNAT entries weren´t changed.
We combined the two internet connections with uplink balancing. We can reach the ftp server in active mode, but as soon as we set the "PASV" command, our connection breaks. Seems like the ftp server can´t reach the external internet connect through upload balancing.
Does somebody know the reason / fix?
Thanks in advance [:)]
