Which ports are used by WinCC flexible?

Configuration Notes:The Ethernet ports are assigned by the IANA (Internet Assigned Numbers Authority). When using a firewall you must enable all the ports specified in the table. All the services listed are handled via the TCP/IP protocol, except archiving via UDP.
The following ports are used in WinCC flexible Runtime:
  Service Port
Web server Access to internal HTML pages (HTTP) 80
Access to internal HTML pages (HTTPS) 443 (SSL)
Sm@rtServer Connection with the Sm@rtServer
(access to the Sm@rtServer for downloading the Java applets with the Internet Explorer)

Panel dynamic 1)
PROFINET IO communication 3) 34964
E-mail (SMTP server) 25
Modicon controller (Modicon channel MODBUS TCP/IP) 502
1) Dynamic port:
The Microsoft Windows operating system automatically assigns the relevant service a free port that can be between Port 1024 and 65534. You must enable this area when using a firewall.
2) Archiving:
Requirement for archiving via an Ethernet network is that the server is enabled.
Communication via PROFINET must be activated in the "Control Panel", in the "PROFINET" Settings dialog.
Note:If you change the ports of the Sm@rtServer, you must change the links accordingly in the HTML pages used. More information on changing HTML pages is available in the Help system of WinCC flexible under "Example: Configuring an integrated web server".
