Since I changed to unlimited with the Genius hardware my FTP connection to a FTP server on a non standard high port number is failing.

My FTP client asks me for my login password and then fails with:
425 Sorry, invalid address given

I have tried Filezilla, CuteFTP and chrome. I think the initial connection on the FTP control port is happening but then something fails when opening the data ports. I have googled the error message and tried all kind of solutions, but nothing worked. Standard FTP on port 21 works for me. Tried passive, active and turned off all firewalls.

When I search the FTP server IP in the NAT mapping table of the genius I find entries like these:

Index Protocol Source IP Source Port Pseudo IP Pseudo Port Destination IP Destination Port
15 TCP PcIp 50676 MyExternalIp 50676 FtpServerIp 80

This to me looks like that my client tried to connect to the FTP server on port 50676 but for some reason that was changed to port 80. Is my interpretation correct?

Any suggestions?

Hi,

This is not something we've tested. Have you tried using Passive mode?

FTP & NAT == serious annoyances. Use sftp.

Yes I have tried passive. Any other suggestions?

Hang on a sec. This was working with Genius before you changed to Unlimited you say?

Yes, this was working with a normal orcon broadband plan using a DD-WRT router. Stopped working since I put in the genius hardware with the new unlimited plan.

Ah. That makes sense.

Can you PM me your username, I'll check if you're on the latest firmware version.

I've upgraded the router, it was on a very old firmware (and being "difficult")

So, fingers crossed that fixes things! Guess we will know soon...

Thanks a lot for the fast help.
I am at work currently, so will test it tonight and report back.

I have tried the new firmware. It definitely updated and the interface looks slightly different.
Thanks a lot for that fast response.

Sadly I still get the same error message when trying to connect.

But the entry in the NAT mapping table entry looks different:

ndex Protocol Source IP Source Port Pseudo IP Pseudo Port Destination IP Destination Port
15 TCP PcIp 50676 MyExternalIp 50676 FtpServerIp 53421

The last port 53421 is the control port of the initial connection:
FtpServerIp:53421

The way I understand it, it should connect to 50676 at the destination. Or am I wrong?
I tried making the PcIp a DMZ to make sure it catches everything coming in and switched of the firewalls.

Filezilla gives me
18:09:45 Status: Resolving address of sapper.seedcafe.info
18:09:45 Status: Connecting to FtpServerIp:53421...
18:09:45 Status: Connection established, waiting for welcome message...
18:09:48 Trace: CFtpControlSocket::OnReceive()
18:09:48 Response: 425 Sorry, invalid address given
18:09:48 Trace: CControlSocket::DoClose(0)
18:09:48 Trace: CFtpControlSocket::ResetOperation(66)
18:09:48 Trace: CControlSocket::ResetOperation(66)
18:09:48 Error: Could not connect to server
18:09:48 Trace: CFileZillaEnginePrivate::ResetOperation(66)

In the browser I get asked the username password before it fails.

So I still think it is a problem of setting up the data port connections.

Any idea?

Just to clarify this. I only got a genius when I changed to the orcon unlimited plan. Before then I had a normal ADSL modem bridged with a DD-WRT router and a orcon broadband plan. The FTP worked on that setup, but stopped working when I switched to the genius modem/router. By the way my genius unlimited plan is still via ADSL.

Does anybody have any further advice?

What is a good FTP debugging client?

Maybe a careful walkthrough with the filezilla setup guide:

Yes, I have tried that but still getting the same error.
I have tried passive and active. Specifying a port range and forwarded those ports. Specifying the external ip address of my client. So far no luck.

I'm stumped TBH. I'll see if I can do some testing with this and let you know.

From the log it appears like you may not have specified the correct external IP within Filezilla.

>> 18:09:48 Response: 425 Sorry, invalid address given

it can change (not fixed like it used to be) so be aware of that.
