I want to be able to access iFolder thru Netstorage. IFolder is behind the firewall and Netstorage is in the DMZ. What ports need to be open between Netstorage and ifolder. I know LDAP and NCP. iFolder listens on 51443, is that the only other port that needs to be opened? Do any ports need to be opened to the ifolder server from the internet, or only between netstorage and ifolder?
