stefanslauritsen Hi, Yes it was resolved in our case. Our issue was with the routing tables applied to the spoke vNET. We had the Default Route and a UDR which was set to the vNET in the Hub. This vNET included the subnet on which the firewall was setup plus other subnets in use for Management Services (Remote Access, Backups, Monitoring etc.) This was causing circular routing and we had to remove this and configure the RT with UDRs for each subnet for the individual services and excluding the subnet on which the firewall was setup. Hope it helps. Good luck
