Microsoft Azure

This guide will show you how to connect your Microsoft Azure cloud to the GoodAccess Gateway via a site-to-site connection using the IPsec protocol.

Prerequisites

You need a virtual network gateway in Azure. If you don't have one, follow this tutorial by Microsoft.

Step 1 - Creating a new cloud connection

Log in to the GoodAccess Control Panel, and go to Network > Clouds & Branches.

Click + Add new, enter a Name (e.g., Azure Production), select the required Gateway, and define the Subnets of your Azure Virtual Network (using CIDR notation).

Choose IPSec Protocol, and click Continue.

Fill out the configuration form (Public IP, Pre-Shared Key, etc.). These parameters must match the configuration you will set in your Azure environment in the next steps.

Click Submit to finish, or Continue to define optional Branch Segments for finer access control.

You may return to the configuration via the Edit button of your Cloud at any time.

Example of configuration:

• Shared Secret - Create a new strong password

• Public IP - IP of your Azure virtual network gateway

• IKE Lifetime (Phase 1) - 8 hours (28800 seconds)

• Tunnel Lifetime (Phase 2) - 1 hour (3600 seconds)

• Dead Peer Detection Delay - 30 seconds

• Encryption (Phase 1) - aes256

• Encryption (Phase 2) - aes256

• Integrity (Phase 1) - sha256

• Integrity (Phase 2) - sha256

• Diffie-Hellman Groups (Phase 1) - 14 - modp2048

• Diffie-Hellman Groups (Phase 2) - 14 - modp2048 (PFS2048)

Step 2 - Creating a new local network gateway

Log in to the Azure Portal, and go to Local network gateways (you can use the searchbar), and click + Create.

Set the configuration as follows:

• Endpoint - IP address

• IP address - IP of your GoodAccess Gateway

• Address spaces - Subnet of your GoodAccess Gateway

The remaining settings are up to you.

Click Review + create and then Create.

Step 3 - Creating a new connection

Go to Virtual network gateways (you can use the searchbar), and select your virtual network gateway.

Go to Connections, click + Add, and set the configuration as follows:

• Connection type - Site-to-site (IPsec)

The remaining settings are up to you.

Click Next : Settings >, and set the configuration as follows:

• Virtual network gateway - Choose from the dropdown

• Local network gateway - Choose from the dropdown

• Shared key (PSK) - Shared Secret (Step 1)

• IKE Protocol - IKEv2

• IPsec / IKE policy - Custom

• IKE Phase 1 & 2 - Must match configuration from GoodAccess (Step 1)

• IPsec SA lifetime in seconds - Tunnel Lifetime (Phase 2)

• DPD timeout in seconds - Dead Peer Detection Delay

The remaining settings are up to you.

Click Review + create, and then Create.

You have now successfully connected your Azure resources to GoodAccess.

Firewall rules

Make sure you allow connections from your GoodAccess Gateway private subnet to the resources in your Virtual Network (VNet) (e.g., virtual machines, databases, etc.).

Depending on your Azure security setup, you may need to allow this communication in:

• Network Security Groups (NSGs)

• Azure Firewall

You may check the status of the connection in:

• GoodAccess: Go to Control Panel > Network > Clouds & Branches to view the tunnel status. Use the Test Connection button to validate the IPsec tunnel itself, or optionally to test a specific system (target must have ICMP enabled).

• Azure: Go to Virtual network gateway > Connections.
