Sophos UTM9 to Azure Ipsec connection

Hi all,

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.

Any ideas?

  • 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
