+===== LAN Access Notes =====
+  * Regardless of LAN Access rules, by default a LANx device is able to reach (e.g. ping) all the router's LAN interfaces (only). This is by design.
+  * All entries in LAN Access are one-way only. For example, if you want hosts on LAN0 to be able to communicate with hosts on LAN1, and vice versa, you'll need two entries in the table to achieve that.
+  * LAN Access is an IP-level access control. Therefore, **all ports/protocols are automatically enabled**. If additional fine tuning is needed (for example, you want to allow only allow port 80/TCP) you'll need to manually configure settings instead.
