Can some one help me to setup connectivity between Azure and on premises infra.

  • Can we setup same network subnet and IP ranges as we have on onprmises to Azure vnet.
  • If not then what are the way to get communicate onpremises to azure ....like I have to setup NAT...etc
  • My concern is...if im migrating few servers in first phase to azure then can they communicate with onpremises.....like first I migrated only app servers over azure and DB servers still on onpremises so can they communicate or not.
  • or what are the best practises to setup network for migrate or sync onprem and azure infra.

    Hello @jahir shaikh

    Welcome to Microsoft Q&A Platform,

    You can use overlapping ranges configuring NAT policies on the Azure VPN gateway side, more info below:

    I hope this helps!

    You can set up a bridge using an extended network - https://learn.microsoft.com/en-us/windows-server/manage/windows-admin-center/azure/azure-extended-network?WT.mc_id=AZ-MVP-5004796

    "Extended network for Azure should only be used for machines that cannot have their IP address changed when migrating to Azure. It is always better to change the IP address and connect it to a subnet that wholly exists in Azure if that is an option."
