Bad / incorrect example: "Only Block Incoming Traffic"

[otheus]

The title "Only Block Incoming Traffic" and provided code make no sense together. The code clearly ACCEPTS all incoming traffic. All outbound traffic is allowed as well.

I'd offer an alternative, but it's not clear what the author had intended.
