Sonicwall VPN with More than 2 WAN connections
I have a Sonicwall Firewall that is currently working with 2 WAN connections in failover with a VPN. It is working fine, however, I need to add a 3rd WAN connection to this and that is not an option in the VPN. What is the best process for this and this new connection must ONLY be activated when the others go offline as it is a cellular backup.
You would be using 2 sonicwall configured in HA as Failovers to facilitate 3 Connections.
you can use the built-in dyndns client to update a dyndns or no-ip.com DNS name eachtime the active WAN IP changes
and make sure in the wan failover group to mark the cellular as afallback only

I dont believe this helps me at all. I have Static IPs, but Need to better understand how to configure the VPN with more than 2 WAN connections since I only have the option for 2 connections
What model Sonicwall do you have?

you mean only 2 WAN ports? or are you talking about primary and secondary IIPSec gateway feature?
Sonic OS 5.6 and above support n-1 WANs
an alternative is to start using Route Based VPN, whereby you setup a route based VPN on each WAN. You then create three nearly identical policy based routes, but each with a different metric

I have currently 2 WANs configured and working with VPN, I need to add a 3rd. The 3rd WAN is working, however, I am unable to add it to the standard VPN config since it limits 2 WAN connections. The route based VPN may work, I have never configured that before. Do you have an article that discusses shows the setup in detail?

Proposed 2 Sonicwalls
Sonicwall1
Wan1 - Original WAN1

WAN1 = Original WAN2
Wan2 = Third WAN Connection

This is the only way I know to do it.
