Plesk is installed inside a VE and windows firewall is configured to pass traffic on 21 port.
However when I try to connect to any domain hosted on this VE via FTP on behalf of any user I receive the following error:
Connection closed by remote host
Even if Windows Firewall is stopped inside the VE, FTP connections still don’t work.
Most likely Windows Firewall runs on the node and FTP service is configured in Local Area Connection, Properties, Advanced, Settings, Advanced, Settings, Services as well. In this case port mapping is enabled and any external queries are forwarded the host itself, and this behavior is by design of Microsoft.
To avoid port mapping, do not configure services in Windows Firewall (Local Area Connection, Properties, Advanced, Settings, Advanced, Settings, Services), but use Firewall Exceptions (Local Area Connection, Properties, Advanced, Settings, Exceptions) instead on the node.
