FTP Binding

Hi

I have change the binding of my FTP site from 21 to 23. Redirect in my router from 21 to 23. The problem is that now I cannot enter in my FTP directories. I'm connecting but never see the directories.I have a response like: The server as return an unreturnable adress, repace by the servers adress.

Is there a place that I have to change port elsewhere that in IIS an the router?

Thanks

hi there

I have change the binding of my FTP site from 21 to 23

 - port 23 is used for telnet sessions - even if you redefine this in your router and in IIS you are ultimately sending the wrong data type down that line.  In addition other clients and ftp products will know this is an error and will return messages such as you are receiving.

Redirect in my router from 21 to 23

- it is likely that redirecting traffic like this on your router will either be mistaken as an attack on port 23 or just return an error.

Are you attempting to change from Active to Passive?  Are you using IIS7 and your clients are faling to connect?  Change your data connection type in your client to overcome this problem - leave your ports as they are or read how to configure active ports:

Hi

I said port 23 but it can be any other port. Examples port 2323 or 2121. I just want to change the port because I have a software to install that is using port 21 and I can't change it.


Thanks.

in IIS 7 there is the "ftp firewall support" page to set the ports.  You then need to enable those ports on Windows firewall both TCP and UDP.  Then you need to enable those ports on your firewall/router and allor port fowarding if you are hosting locally or "open ports" if it's outbound traffic.
