Hi
I'm after some advice setting up a high availability SonicWall system. I have a client who currently has 2 Arista 10G Switches that are connected together via MLAG, this is the LAN network which is currently has 3 VLANS.
The client has just updated its Wan connectivity and now has 2 incoming Wan connections from two different ISP.
The client wants a HA firewall solution, they have shut one of their offices, so now has 2 Sonicwall NSA 2600 to do this with. I get how to setup the HA but not sure how to approach the connection with the MLAG'ed Arista's to get fault tolerance incase one of the Aristas fail.
Any tips on the Wan connectivity setup? It would be nice to have ability to direct certain traffic to certain ISPs but with automatic failover if one ISP fails to the other.
