Thanks first.
What's the difference between Filezilla Server and Filezilla Server Interface when setting a inbound Rules in Windows Firewall with Advanced Security?
target：
When finished the installation for Filezilla Server ,I need to ensure that current branch office vistior's accesses,and deny the access from headquarters or other branch office.
question：
When setting a inbound Rules in Windows Firewall with Advanced Security,do both rules(server.exe and interface.exe) need to be set?

The FileZilla Server Administration Interface only makes outgoing connections, to the FileZilla Server service.

Yes you're right.
I disabled the rule for interface.exe，and kept the rules for server.exe.It works properly.
