Why doesn't the ANY-ANY-ALLOW-ANY Rule work?!

Yesterday, I tried to open up everything to troubleshoot an ongoing connection issue. I created an ANY-ANY-ALLOW-ANY rule to let everything in on a network with only a single PC having no security requirements.

Despite the ANY-ANY-ALLOW-ANY rule, Packet Filter showed all kinds of stuff still getting dropped. Why did that happen if had the above rule activated and working?

Got DNAT?

Yes, real IPs on the Internet were dropped. IPS was inactive and no DNATing. What else would cause those packets to be dropped?

I can post a sample of the packet filter log if anyone is interested in seeing that.

Sorry, INT is Internal network, not Internet.

My point was, if you're not using real IPs internally, you need Masq and DNAT setup.

The any-any-any rule is a bit deceptive. It will still block packets to the firewall interfaces.

So try adding Any Any RED (Where RED=external nic)
