When we connect two networks via VPN connection, we only allow certain traffic to pass through (In most scenarios). This is the normal security best practice. We normally use a firewall to do this. When it comes to Azure, we may also need to connect virtual networks . In such situation, By using Azure Firewall, we can control the traffic between virtual networks. More info about Azure firewall…
In this blog post we are going to learn about Active-Active Azure VPN gateways. There are two methods to connect two virtual networks.
1. Azure VPN Gateways
2. Azure VNET Peering
Azure VNET Peering
Azure VNET peering allows connecting virtual networks seamlessly via Azure backbone infrastructure. This is similar to inter-VLAN routing in on-premises networks. The traffic will not pass via the…
By using source network address translation (SNAT), we can translate a local IP address, a pool of local IP addresses, or even a subnet to a specific public IP address for outbound connections. This is important as it will help to control traffic flow through firewalls by using ACLs. In Azure, we can do SNAT by using Azure NAT gateway. This allows virtual machines in the subnet to use a specific…
Azure VNET peering allows connecting virtual networks seamlessly via Azure backbone infrastructure. This is similar to inter-VLAN routing in on-premises networks. VNET peering can use to connect virtual networks in the same Azure region or different Azure regions. If it is between regions, we call it “Azure Global VNET Peering”.
Global VNET Peering has following benefits,
• Low latency and…
