nat port range not completly forwarded

Hi Martin Seidel,

Thanks for reaching out to the Community!

Hi Martin Seidel,

Thanks for the update. 

Is Anti-Dos/Flooding protection configured for UDP on your firewall? 

I would suggest you run a packet capture on the firewall on a port number that shows blocked while running the test to identify if the traffic arrives at the firewall or not. 

• tcpdump -nei any portrange 9044-9070

Reference KBA: 

• Sophos UTM: How to capture packets and download the Packet Capture

Also, check the packerfilter logs concerning blocked ports.

Thanks,
