Joing AZURE vNIOS to external grid (Public IPs NO nat on the grid side)? [ Edited ]

[#1]

How does this work?  I have a grid on the public internet without any NAT.   

I want to join an Azure member to that grid but struggling with it. Within Azure I have a public IP assigned to LAN1 of the vNIOS instance like so:

Azure grid member: 55.66.77.88 > 10.10.10.4

Grid Master: 11.11.11.11

I configured the azure member on the grid with its 10.10.10.4 ip as LAN1 and then enabled NAT group and configured the 55.66.77.88 IP.  I did the same on the azure memebr but neither way allowed that azure member to join the grid.  I know there is IP connectivity between them but still unable to make this work.

This works as long as your allowing the necessary traffic between the two.

Make a long story short configure NAT group on the grid member in the grid and the to-be member itself and it will join without issue as long as the ports are open.

Good Day, did you get this working with the NAT groups, I am working on a similar situation with no luck.

Thanks

As connecting the Kubernetes cluster to Azure Arc enabled Kubernetes is a free the Azure Portal without requiring a public IP on the virtual machine.
