I have a customer with a Sophos UTM9. I have a Virtual Network Gateway setup in Azure.
I am getting egress traffic in Azure, but no ingress. The Sophos appears to not be sending the traffic back.
Logs are showing "Invalid Message ID".
We followed this tutorial 100%.
I have had two experience network engineers look at this, and one a supposed Sophos expert.
Hi Mike and welcome to the UTM Community!
Do you learn anything from doing #1 in Rulz (last updated 2021-02-16)?

Did you fix this?
I got it working, but only for 8 hours at a time. After 8 hours the connection would drop. Then 8 hours later, it came back online again. Etc. Very annoying,
So we paid for ExpressRoute instead, that works 100% of the time
