Branch Controller Security

Anyone out there using branch controllers and if so how are you securing the interface connecting to the ISP?

I want to apply an ACL to mine that allows only the absolute required ports based on source and destination.  I am picturing an inbound ACL that allows UDP4500 from my master controller IP and maybe some ICMP traffic for the WAN Health check option.  Do I need something for activate.  Anyone can share an example ACL with me please?
