CtrlX Firewall app - Problems with SIP

[Dominik3]

The application looks as follows:

The SIP server (miniSipServer) has the IP address 10.138.141.40 and is connected to XF10.
The SIP client (Bosch Praesensa controller) has the IP address 169.254.255.20 and is connected to XF51.

The ctrlX core uses NAT for the translation. I manged to configure the access to the webserver of the controller and also to access the OpenInterface of the controller which have a fix port. But I have problems to configure SIP. The client can register to the SIP server, but the when starting a call, it does not start to send RTP data.

Does anyone have experience with SIP and the firewall app? Any tips or is there an application note for SIP + Firewall?

The documentation for the Firwall app is here: https://docs.automation.boschrexroth.com/doc/4179973358/introduction-and-overview/latest/en/

But it does not explain how to forward a port range from one side to the other. At the input configuring a range is staring forward in the DNAT entry but how to specify the used ports at the SNAT?

@Sgilk since you helped me succesfully with my forewall problem do you have any suggestions for this guestion? I do realize it is in the wrong part of the forum should have been the IoT section.

@Marc-Smaak ,

Is this at all related to the original post on this thread?

@CodeShepherd, we may want to split this into seperate posts if not.

Yes it is, I am supporting @Dominik3 to get this working. I believe he got something working now so I will ask to update this case
