I just witched my internet over to a MPLS network with a cloud based firewall. So all routing and firewall configuration is handled by my internet provider. This is working just fine but I want to have a backup internet connection as I did before. The problem is that router is on my network so setting it up as a external connection causes firewall panic. At this point I am using the mpls router as my gateway and my clearbox as the dns/dhcp. Multi Wan may not be the way to do this but are there any thoughts on how to do this? Any input is greatly appreciated.
