Hi all, I have an ExpressRoute connecting an on-prem network to a VNet. I have an Ubuntu VM in that VNet which I can successfully SSH to, ping etc from my workstation. However this VM cannot access the internet. I can't see anything in the NSG attached to the VNet that appears to be blocking outgoing traffic but I'm no expert at this so who knows. FYI the VM does not have a public IP (dictated by policy) and a static local IP.
How can I start debugging blocked outgoing traffic form a VM?
