Hi,
I have a Mikrotik RB951 with several client computer.
I have problems with client that want to access a public FTP.
All my FTP client behind the Mikrotik, receive a "Connection reset by peer" error. Authentication goes well, but as soon as I use the mput command the error appears.

When I remove the mikrotik and replace it with a Comtrend ADSL router it works.

The mikrotik FTP service is disabled.
I even change the port in order to be sure.

I have created a rule that allows all forward traffic for the ip of the FTP server, but still nothing. I always get the same mistake.

Did you have an idea please?

Thanks.

Hello

Sorry for the wait time, I have solved my problem since, just disable the FTP services in "IP -> Services", but let's enable the FTP service ports in "IP -> Firewall -> Serices ports ".
