 ====== PFSense - Troubleshooting - Firewall Blocking an Internal Address ======
+===== Check the Firewall Logs =====
+Check firewall logs at **Status -> System Logs -> Firewall**
+----
+===== Try to open a pass-all rule =====
+Add a pass-all rule at the top for that VLAN on pfSense and enable logging.
+If this allows this through then go through each subsequent rule to see if there is a problem.
+----
+===== Check ARP tables =====
+Navigate to **Diagnostics -> ARP Table**.
+On your client, when you try and ping pfSense on 192.168.1.1, you should see your MAC in the ARP table.
+Check the MAC address is correct, i.e. matches up with pfSense MAC address.
+If the MAC address does not match the pfSense MAC address:
+  * There may be an entry for the IP in the ARP, so try to delete it.
+  * The system should automatically add this in again correctly.
