Ftp error. Stops during upload

[Krisxxx]

Hi
I have a strange problem. After a new install of Debian Lenny + Ispcp 1.0.7 i have problems uploading files to my sites. Im using Cuteftp and the upload stalls after a few second. Cute ftp says "cant open dataconnection". I see no errors in the proftp log. Anyone tried this before?

Looks like a problem with a NAT router and PASV FTP settings. Try to disable passive mode in cuteftp and see if it works...

I tried it and some of the files doesnt get through. My router is a Thompson TG712. Can i set something in the router? Recently changed from a Zyxel router and there was never problems.

Btw. the port 21 is opened in the router.

Could it be something in the server? Same problem with Filezilla. Its strange that i can connect and the suddently it says:" Server can't open data connection." & "425 Unable to build data connection: Connection refused".

Still with the same problem. Anyone?
