Can two vms (on separate virtual networks) ping each other? If so, how

Question

{VNET1}

(VM1)Windows VM (testserver)- Private IP address = 10.0.0.7

VNet Address space: 10.0.0.0/16

Subnet Apps Address space: 10.0.0.0/24

{VNET2}

(VM2) Linux VM {sonicwall} private IP address =172.16.0.4

VNet2 Address space: 172.16.0.0/16

Subnets Address space:

LAN X0: 172.16.1.0/24

WAN X1:172.16.0.0/24

Description: I have a windows vm (test server), and I just deployed a linux vm with SonicWall NSv (Firewall/Security/VPN/Router)-BYOL appliance on separate virtual network.

Assignment: Need to ping Sonicwall LAN IP from windows vm. Need step by step

Quick Notes and questions:

-The windows vm was deployed without an assigned public ip address

-Can this assignment be done without vnet peering and route tables?

Answer 1

Hello Steven O,

Thanks for your question.

By default, 2 Separate Virtual Networks cannot communicate with each other.

Since you want to ping the SonicWall LAN IP from the Windows VM. VNet peering is the most straightforward approach. You don't need a public IP address for the Windows VM as long as communication stays within the peered virtual networks.

However, yes it can be done if you dont want to use peering or route tables. You can leverage alternatively VPN Gateway.

See the documentation here if you want to implement: https://learn.microsoft.com/en-us/azure/vpn-gateway/vpn-gateway-howto-vnet-vnet-resource-manager-portal
