Configure Firewall of a WinCC OA server with MxProxy enabled

[fandersen]

Hi together,

on our WinCC OA servers I want to configure the firewall, the MxProxy is enabled (default port 5678).

In addition to opening port 5678 (TCP) on the firewall, do I also need to open port 5678 for UDP?

I can imagine that I might need to do that for having the alive mechanism (TCP and UDP) working correctly, but I am not sure if this is even realized with MxProxy. I couldn't find it in the manual.

Maybe someone knows for sure?

Cheers
Florian

Information for the configuration of the MxProxy manager you can find in the WinCC OA Documentation and the Security Guideline for the version you are using:
