I'm trying to configure my DNS-323 to be open to the outside world for connections of FTP over SSL/TLS (my router is a D-Link DIR-655). But unfortunately something is not working.
The connection is established but when using TLS it gets stuck on the LIST command. I already tried to forward the ports 989 and 990 (besides the standard 21 for FTP) to the DNS-323 from my router, using the Port Forwarding Rules table, but it didn't work.
Currently the DNS-323 is on the DMZ of the router, so it shouldn't be a firewall problem, but, when I connect directly to the internal network address of the DNS-323 everything works fine.
Another problem, is that standard FTP, when I put DNS-323 behind the firewall, simply stops working (getting stuck also on the LIST command).
Any ideas of what I should do to make this work?
Thanks,
Miguel
