Hello everyone,
I have been working on this now for a couple of days, and now just completely frustrated. I am attempting to setup an FTP server on a windows box to handle the backups for our off-site devices, like servers and such. I am using the Filezilla FTP server, and an FTP script to accomplish this on the machines in question. I am testing the connection with just the Filezilla client. All I get out of Filezilla is when connecting is:
425 Can’t open data connection for transfer of “/”
I login fine but it appears when getting a directory listing. Server connections are fine internally. and regular FTP works fine, it’s just FTPS.
Network setup:
- Peplink Balance 305 Firmware 6.3.1 build 3471
- Dual Wan connections
How it’s setup:
I have added my FTP windows server as a server in the configuration. Then under services I have added 3 entries
FTP: WAN1 to FTP server, port 21
FTPS: WAN1 to FTP server, Port 990
FTPS_Passive: WAN1 to FTP server, Ports 50010-50074 (passive ports set in filezilla)
After setting those, the connection fails with the 425 error. I thought since we have the dual WAN ports that it might attempt to respond via the second IP address. so I added the following to outbound policy:
FTP: Persistence From FTP Server to Any, Port 21
FTPS: Persistence From FTP Server to Any, Port 990
FTPS_Passive: Persistence From FTP Server to Any, Ports 50010-50074
Still nothing, same error.
Dumbfounded now I added the following to Access Rules:
INBOUND
FTP: WAN1 to FTP server, port 21
FTPS: WAN1 to FTP server, Port 990
FTPS_Passive: WAN1 to FTP server, Ports 50010-50074 (passive ports set in filezilla)
OUTBOUND
FTP: from FTP server to any, port 21
FTPS: from FTP server to any, Port 990
FTPS_Passive: from FTP server to any, Ports 50010-50074 (passive ports set in filezilla)
Still same error.
I have no Idea what to try next. Never had these issues before, set this kind of thing up multiple times over the years.
Any help would be greatly appreciated.
Thank you.
