Internet redundancy for both inbound and outbound traffic
So we need to replace our very much outdated internet load balancer and firewall. We are considering using a pair of highly-available Meraki MX84's for this and I am trying to figure out how could configure fail-over between two internet connections. We have a primary fiber internet connection and a backup cable modem.
Is it possible to configure the mx firewall to NAT inbound traffic from either internet connection for services hosted on our network? How could we setup DNS ensure that internal services are available on either connection?
