+===== LAN Access Notes and Troubleshooting =====
-===== LAN Access Notes =====
+  * On releases r2025.4 and earlier, regardless of LAN Access rules, a LANx device was able to reach (e.g. ping) all the router's LAN interfaces (only).
-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.
+  * On r2025.5 and later: FreshTomato LAN interfaces can only be reached from within the same subnet. Thus, a device at 192.168.10.10 can only reach the router at its address on the same subnet e.g. 192.168.10.1.
-All entries in LAN Access are one-way only.
+  * All entries in this menu are one-way only. If you want hosts on LAN0 to communicate with hosts on LAN1, and vice versa, you'll need two entries in the table for that.
-For example, if you want hosts on LAN0 to be able to communicate with hosts on LAN1,
-and hosts on LAN1 to be able to communicate with hosts on LAN0, you will need to have two entries in the table to achieve that.
-LAN Access is an IP-level access control.
+  * LAN Access is an IP-level access control. Therefore, **all ports/protocols are automatically enabled**. If additional fine tuning is needed (for example, to allow only allow port 80/TCP) you'll need to manually configure the settings for that.
-This means that **all ports/protocols are automatically enabled**. If additional fine tuning is required (for example, you wanted to allow only allow port 80/TCP) you will need to manually configure settings instead.
