@JonathanLee said in To Default Reject Or Block That is the Question.:
I wanted to share this with you incase you ever asked the question what the difference its between block or reject...
A block just drops the packet, without any other response. A reject sends an ICMP message back advising why. You want to use block on the WAN, so that the attacker has no confirmation there's something there. Use reject on the LAN, so that an issue can be identified.
