ubuntu 11.10 and ftp problems

I would not say im new at linux I have been using it for years but this is the first time that I have had to setup a server. well let me go thou the problem. I have followed http://www.howtoforge.com/perfect-server-ubuntu-11.10-ispconfig-3 to the Tee. I have setup everything that it states. I have setup a user in ispconfig with a website, and ftp account. Now the problem is I cant access the ftp account through a ftp client I have tried everything from changing from passive to active. All ports are open. I have tried both port 21 and 22 (FTP AND SFTP) but my server will just not allow me to access it.

In filezilla i get this error
Error: Authentication failed.
Error: Critical error
Error: Could not connect to server

I have DMZ my router and opened both ssh, ftp and sftp ports.

Im just at a complete loss apart from this the server is working.

If someone could please help I need to get it up and running as soon as possible.

 

What's the output of

Code:

netstat -tap

?

Are there any FTP errors in your logs?

Looks ok. What about the logs?

Can you also post the output of

Code:

iptables -L

?

right I have gotten access through my local lan but I still can not get access from a external ip e.g. friends house. I still dont think it is a router problem as i can reach my server but it will not allow ftps access from a external ip

 

Please check your router settings. Make sure ports 20 and 21 are open.

 

Well i have checked my router porst 21 and 22 is deffently open i have even pinged my server from a external ip and it is open so it has to be a problem else where
