Dell SonicWall NSA 3500 Firewall Cluster For Sale

I have two Dell SonicWall NSA 3500 Firewalls for sale. They are HA units, so one is the primary unit and the other is the cluster unit. They come with the HA cluster licensing and VPN licensing as well as SonicWall software upgrades and downloads. They work great and are still very widely used firewalls. This is a steal as they were purchased in the realm of $8000 only 3 years ago.Specs:
