Copy link

If you created the Network Sensor host in a different virtual network to the traffic sources you want to monitor, you must enable Virtual Network Peering .

If the Network Sensor host and the traffic sources are in the same virtual network, skip this article and continue to Configure the Azure vTAP.

⚠️

Address spaces must not overlap

To enable Virtual Network Peering, the address spaces of the Virtual Networks being peered must not overlap. Azure displays an error on the Address space menu of the virtual network if the address prefixes overlap.
