Question about failover\dual WAN

I have a USG110 with dual inbound WAN.  The setup is I have two strands of fiber coming in, one from a Northbound loop and one from a Southbound loop.  Obviously, I'm setting up for redundancy so that if one feed dies, I'm good on the second loop.

So, I set up a WAN trunk, added my two WAN ports to it and set it to default.  I also did all of this remotely and I stayed connected.  I never dropped connectivity for the rest of the night.

Then, oddly enough, the primary loop went down.  After that, I was never able to get connected remotely again.  I had to go onsite, power cycle the router, and everything came back up.  I'm going with the failover failed and didn't fail back, but I wanted someone to chime in and tell me what they think.  

Also, I have some NAT rules in the router.  For example, port 443 comes in on WAN1 and redirects to my IIS secure server.  

After I added the WAN Trunk, I "expected" to alter my NAT rules and redirect all inbound from the WAN Trunk to my respective servers, and I do not see that.  What's the point in having a failover internet connection if I can't alter my NAT rules and DNS to make that happen.

Thanks for your help.

    You should create NAT rules both for WAN1 and WAN2.
    So, 443 will be redirected in both cases.
