I have been trying to setup a routed VPN to Azure with no success whatsoever. I followed the steps given in https://docs.opnsense.org/manual/how-tos/ipsec-s2s-route-azure.html. The tunnel is shown as UP from both Azure side and Opnsense side. But not traffic is flowing in the tunnel. I am not able to RDP into any servers in Azure.

If I change the VPN type from Routed to Policy based VPN then there is no issue and everything works as expected.

When I check the traffic in the tunnel interface it shows as zero.

Has anyone been able to get Azure working in t he latest firmware?

Hi

Does anyone have faced this issue with OPNsene on configuring a s2s tunnel to azure?

Set outbound Nat to manual and add the rules you need for internet access etc.

Hi

Thanks for the reply. Could you please specify on what the configuration for outbound nat should be?

If you have none then just your LAN, direction any on Interface WAN

That worked like a charm. Now I am able to connect to Azure from my on premises systems. Thanks for helping out

So it appears that there is indeed a bug in OpnSense when Azure is configured as the NAT rules get automatically generated.

Is there a fix in the horizon where we do not need to manually change the configuration? Else it may be a good idea to get the configuration guide updated.

I updated to 19.7.3 and it seems to have solved the issue
