At this point, you should already have your Main Office SonicWall configured for the VPN by following Part 1 of this guide. Now, we will configure the Remote Office SonicWall:

Remote Office:

After logging into the web interface of the SonicWall at the Remote Office, Click on the Wzards button in the top right corner:

Select "VPN Wizard" from the list and click Next:

Select "Site-to-Site", and click next:

Give the Policy a name. It can be anything, just make it something descriptive. Enter the exact same Preshared Key you entered on the Main Office SonicWall. For the Remote Peer IP Address, enter the static IP of the remote site. You may also enter a domain name (main.mydomainname.com):

For Local Networks, I chose "LAN Primary Subnet". For Destination Networks, choose "Create New Address Object..":

Give the Address Object a descriptive name. Just remember, this will be the Main Office network that you want to access over the VPN. For the Zone Assignment, choose LAN. The type is Network. Then enter the Main Office Network and Netmask:

Choose the Address Object you just created as your Destination Network and click Next:

You can leave the security settings at the default, just remember, they must be the same on the Main Office SonicWall:

Click Apply and Close to complete the VPN Wizard:

This concludes the configuration of the Remote Office SonicWall. Unless there are any other complicating issues, the VPN should be online and working now. Click on the VPN tab to view the status of it. You should see a green dot next to your VPN. This signals that the VPN has been established and is online. You should now be able to access resources across the VPN. In my example below, I can ping a server at the Main Office from the Remote Office:
