Had an issue where my LAN connection to the Internet was disconnected due to the switch failing that connects the LAN to the sonic wall. This cut off all my VMs including the exchange server. I also had no way to remote in. Didn't realize until I went to the server room and saw the switch down. I actually had another switch fail simultaneously.
My question is how can I implement redudancy? The sonic wall is a NSA 240. It has one port labeled LAN which I use for the LAN. It also has four other ports labeled X0 through X4, I think from memory. I use X0 for the primary WAN and X2 for the backup. Can I use one of those X ports for alternative LAN to a second switch (still have the LAN port connected to a switch as the primary connection)?
Thanks a lot. This caused a huge problem during the recent hurricane and subsequent implementation of the DR plan.
