Secure method to transfer file to DMZ and back
as far think, there 2 methods transfer files internal network web server in dmz. meanwhile, specific protocol , rule need enabled on firewall.
method 1. share out folder on web server, copy file through smb protocol it. (smb protocol , tcp 445 port requires open on firewall)
method 2. install ftp service on web server, upload file through ftp protocol it. (ftp protocol , tcp 20/21 port requires open on firewall)
network ports used key microsoft server products
