Looking for some advice on how this will work for us in a disaster recovery scenario. Right now we are like most businesses on a fiber internet connection, and have fiber between our remote offices. If in a disaster we lost fiber to our headquarter facility, we want to use the Verizon WAN HWIC solution to get us by until fiber service is restored. What would this look like for us when the disaster happens? How would I route us out through Verizon?
Right now we have everyone with a default gateway of our main switch. That main switch has its default gateway as our firewall. When the disaster happens, do I just change the main switches default gateway to my new router with the Verizon HWIC card in it?
I know this will only allow for outbound traffic to the internet, and nothing inbound, but will that work?
My other more pressing concern is, will this be safe? Since traffic will now be routed through Verizon and a router only, no firewall?
Any thoughts or suggestions would be appreciated!
