we have multiple branch offices which we want to connect using Sonicwall router. There is a NSA-2400 at our main location and NSA220 at the remote branches.
We have a MPLS network and we want to create a backup vpn via internet. Via MPLS the packets should be transferred without a vpn connection.
Since the firewall is working zone based, depending on which route is active, the packets either enter or leave through the VPN zone or MPLS zone (X2).
How can I set this up to create access rules only once and not twice (for zones MPLS and VPN)?
