Implementing proper Firewall Rules is not my favorite. The below is the result of extended trial & error attempts when devices were not recognized and/or talking to each other. I know... not pretty! Though the Security Advisor purports to claim all is well, I'm still cautious especially when I see over 22,000 Hits in 24 Hours. "IPv4 Compatibility" appears to be too popular.... Is this a normal count for most?
