12 This feature is to filter the unwanted LoRaWAN packets. Purpose is to save the upstream traffic especially for a 4G cellular connection. If configured, gateway will process filter for below two types of message:
13
14 * Unconfirmed Data Up
15 * Confirmed Data Up

61 * Fport Filter configured to (% style="color:blue" %)**Level=2**(%%). If the Fport in the list does not match the Fport received by the gateway, it will be dropped.
62
63 In this case, we set Fport Filter Level=0 and add the fileter (server | fport | 0), when the gateway receives a Lorawan packet with Fport=0, it will be dropped.

128 The Gateway FPort filter will check all the below LoRaWAN message: Unconfirmed Data Up & Confirmed Data Up. If the packet's FPort doesn't match the FPort setting, it will be dropped.
129
130 (((
131 By default , this value is 0 means can upstream all packets with any FPort. We can set to other FPort so specify only one FPort works.

137 In case we set the FPort filter to 45, and the End Node send a packet with Fport other than 45, it will be dropped.

143
144 Gateway will use a DevAddr mask to check if the Unconfirmed Data Up & Confirmed Data Up packets match the mask . If not, gateway will drop it.
