I'm having problems getting Network Security Groups to work in Azure classic? I’ve removed some existing endpoint mappings and switch to NSGs so I can block some outbound ports.
I’ve created the classic NSG, added some rules, removed the endpoint mappings from the VM and linked the NSG to a classic VM but I can’t connect to it externally. I have a similar NSG setup for ARM servers in the same subscription and that works as expected.
The network monitoring tools, like IP View, seem to be ARM only, so any ideas?
