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?

Based on this message, it may be this is nothing to do with Genius but the fact that you've gone to a different IP address pool and reverse DNS isn't working the way the FTP server expects.

You can try your old modem if you want to rule it out completely. It should be able to work if you enter the DSL credentials (but you won't get VoIP service).

HTH!

It looks like you are on a range we havent added reverse records for yet.
Dont know if that will fix it but the reverses are being setup at the moment.

Once done for the range you are on ill let you know if you feel so inclined to test again.

Hi Paul

Since yesterday evening my ftp connection started working again

. I assume that you have added the reverse records and that would have fixed it. Maybe you can confirm.

So that solved my problem. Thanks a lot for your help. It was a bit of an obscure error.

Cheers
