Is there an easy way to reject all incoming packets except those that come from certain IPs? I can't find any way via iptables or via the GUI

See this great iptables example:

In your case it'll be a whole lot simpler, all you'll need are the initial drop rules for all traffic, then a rule or two to allow XYZ ip in.

Thanks!! I'll try that tonight. Or a variation. I just wanted to make sure it was possible and easy mostly, before I started down that path. But you gave me a good start. I appreciate it.
