I have a 2820vn and have recently become aware that I am unable to connect to any external FTP sites. My FTP client (filezilla) initally connects to a site but then displays the error message "ftp error 425 no data connection". Does anybody have any idea what is going on here?

Did this ever get resolved, we have the same router and same issue, I have upgraded the firmware which doesnt resolve the issue, have tried calling the premium support number but nobody answers it!

I have the same router and I constantly access FTP sites all day with my job. No problems at all here.

Out of interest, there are a number of issues regarding the use of NAT routers and FTP.

Some light reading: http://www.ncftp.com/ncftpd/doc/misc/ftp_and_firewalls.html

Long story short, I ended up having to DMZ my FTP server to get things working correctly. Obviously this is the other way around for you, but may be useful to know.
