I am just setting up my Astaro firewall and have run into a problem.
My ver is 5.1+all updates. I have an internal linux server doing email/web/ftp in the dmz.
What I want to do is set the firewall so people connect to port 2121 for the ftp server the firewall will then take connection from 2121 and translate them to 21 on my server.
The d-nat/s-nat rules won’t seem to let me do this.
What I did was set the Service to my custom one FTP2121 and then set Service destination to the standard FTP21. But I get this error.
“The matching service protocol is not the same as the translated one.”
Can I not do this with Astaro. With smoothwall it worked with know problem.
I do not want to change the listening port of my server to 2121 for reasons I wont get into.
