SonicWall

This guide will show you how to connect your SonicWall device to the GoodAccess Gateway via a site-to-site connection using the IPSec protocol.

Step 1 - Creating a new branch connection

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

Click + Add new, enter the Branch name and subnet, and select Gateway.

Choose IPSec Protocol, fill out the Settings configuration form, and click Save.

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

Example of configuration:

  • Cloud/Branch subnet - Subnet of your local network

  • Shared Secret - Create a new strong password

  • Public IP - IP of your SonicWall

  • 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

Step 2 - Creating new address objects

Log in to your SonicWall device, and go to Object > Match Objects > Addresses > Address Objects. Click + Add.

You have to create two objects - gateway and subnet.
