If you run the SQL Managed Instance Prepare Subnet script against a vnet & subnet which matches the network requirements.
It will display warnings for:
[NSG] -Allow outbound TCP traffic on port 80
[NSG] -Allow outbound TCP traffic on port 443
[NSG] -Allow outbound TCP traffic on port 12000
Even though the network security group has these ports/direction/protocol allowed.
To see if I had somehow missed something, I have another VNET & subnet in a separate subscription that was created automatically by the SQL Managed Instance portal wizard (i.e. not manually created) and it produces the same warnings (in fact it also has warnings about the Route Table not having 0.0.0.0/0 -> Internet route defined).
