Hello, I have 2 Sonicwall's an NSA 3500 and an NSA 4600, I also have 2 internet circuits one is 20Mb and the 2nd 100Mb, I know I can't do Sonicwall failover but would like to set it up so we can have some level of redundancy (even if we have to move a cable), just wondering how others are accomplishing this - the new 100Mb fiber circuit can be handed off as fiber or Cat-6<br />
the 20Mb circuit terminates at a Cisco 2921/K9 router and drops of to ethernet. I know the NSA 4600 has some cards available where we could hand fiber off to it - not sure on the 3500. The intention is to keep both circuits up the 20 for utility functions and the 100 for corporate internet etc.. It would be great if the 100Mb went down to switch it somehow or have some kind of box in front of the firewall that could do this and provide for failover. &nbsp;<br />
Any ideas would be greatly appreciated.<br />
Thanks for any help

Sonicwall and WAN Failover

Network design and methodology, also known as network architecture, is the design of a communication network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats used in its operation. In telecommunication, the specification of a network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are compensated.
