The modules and Web Designer uses well known ports FTP (21), HTTP (80), SMTP (25), DNS (53) ,DHCP (67,68), NTP (123),SNMP (161,162) and Schneider application protocol (502). It also uses un-privileged ports (greater than 1024) for database access (depending on DB server configuration) and publish subscribe mechanism (6010 + dynamic port allocation). Then if you plan to use Web Designer through a firewall, you must check if all ports are opened for your module.
