Need Solution for Private Peering Express Route in azure issues

id flag

I have Hub Spoke VNet Architecture and and express route attached to my hub VNet. I want to understand following points and see if there's something that can be done to solutionize this ?

  1. Since Express Route is private peering and attached to hub VNet all my VNets are published over express route, Is there's a way i can restrict what needs to be published and what not over express route from azure.
  2. I want to publish Public IP over express route and NAT Inbound connection to private IP. For this i tried setting up some network but i Guess its getting dropped. Can you please suggest what is wrong with this . enter image description here

If you don't want a specific vNet to route traffic over the express route then you need to override the Express Route routes with a more specific route table. In the vNet you can do this by attaching an Azure Route Table with a default route going out to the internet, for your on-premises resources you would need to configure this using whatever network stack you are using.

Your second issue is likely down to asymmetric routing. Traffic is coming in your public IP, but out your Express Route. You would need to configure routing for that vNet to send the appropriate traffic directly out to the internet.

Thanks Sam, I added Route to gateway subnet to route traffic to NVA, but traffic is not reaching to even NVA.

That won't help, the traffic needs to go out the same way it came in, back out over the public IP.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
