TFTP und Magenta TV

[Gortosch]

Good evening,

I'm desperate right now. I'm trying to get my new 401 magenta TV receiver working. The first step is TFTP. I can't get the receiver to download its update over TFTP. I already tried Outbound NAT and Port Forwarding. But without success.

Magenta_TV stands for the receiver e.g. 192.168.10.6

Outbound NAT:
WAN Magenta_TV udp/ * * udp/ 69 Interface address * YES
or
WAN Magenta_TV udp/ 69 * udp/ * Interface address * YES

Port Forwarding:
WAN UDP * * WAN address 69 (TFTP) Magenta_TV 69 (TFTP) <- I'm not sure about this at all.

The problem is that the request to the server goes via UDP 69 and is then answered with another port. What is the port range here? Or have I understood something completely wrong?

I don't even want to think about the following problem with Multicast.

Does anybody already have a solution or can please help me? For pfSense there are probably already some solutions especially for the TFTP topic. But for OPNSense unfortunately very little or nothing at all.


Greetings
Sven
