How to configure site to site VPN

In this first video of 3, we are configuring a site-to-site VPN between two SonicWall firewall where both firewalls have a fix IP. Then we briefly cover how to do access rules within your VPN, then cover troubleshooting and finally we change the remote site firewall to a dynamic WAN IP (DHCP) and explain how to build VPN with one site having a dynamic IP.

If you have more complex needs in terms of VPN, I personally advice to go with tunnel interface VPN
