Port Forwarding

Hello,

Can anyone help me out with the Port forwarding in ASA 5520

My Client from outside connecting to My inside SFTP server using port 21 and they use secure key but when they trying to connect client geeting an error authentication fail

so we decide to create another SFTP on port 6000 my internatl server and client use the same port 21 and on my firewall I have to do redirect the port so the client connect to the port 21 is redirect to port 6000 on my internal server

I already have static nat for my SFTP for my other client they connect using active directory and they dont have nay issue and I can't remove the existing configuration

my thinking is that to configure another ip private ip on the SFTP 2nd nic and assign public ip for SFTP and do port forwarding this is my idea

please let me know

please see the attachment

Thanks
