Firewall settings to allow all domestic access
I am developing a small website for my condo community and would like anyone in the community to be able to access it. My application has server-side SSL and password authentication for all clients. So, I am not terribly worried about allowing general access from IP's that originate in the US. But I have limited knowledge of configuring Firewalls and know little about APF and CIDR rules. It seems way more arcane than I would have imagined. How can/would I configure APF to limit users with US-based IP addresses? (BTW, I do know about the APF allow and deny files, but I don't know very well how to express IP ranges and certainly don't know how to restrict them to be from domestic sources.) Thanks for your help.
