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?
