It's not possible to have 2 default gateways. That's not a FreeBSD thing,
it's a violation of the routing system.
If you want failover between two different gateways, you'll need to set
up BGP of some other routing control system to automatically adjust routes
as needed. An explanation of BGP or any similar routing protocol is
beyond the scope of an email explanation - if that's what you need, I
suggest you look to amazon.com or similar for research materials.
