Hi @Tom de Smidt | Hermac BV ,
the IP address range of the Branch office is "known" by Azure infrastructure as well?
For me it sounds like a routing issue.
Azure needs to know the branch office networks and the main office networks.
The main office needs to know the branch office and Azure networks.
The branch office needs to know the main office and Azure networks.
If I understand correctly the traffic between branch office and Azure will be routed via main office?
This means the routing should be configured properly in all related networks.
