I tend to find this site handy when it comes to the likes of that sort of subnet - http://www.subnet-calculator.com

Perhaps I'm mixing things up here, but isn't the WAN IP irrelevant to the subnet? That's the routers job - to shift traffic from one to the other. I would give the routers/firewall the LAN IP of .49 though as the first on the subnet.
