Can more than one ic880a gateway run behind a typical home firewall?

Gateways not only forward packets, but also need instructions from the backend:

Just for future reference, [LoRaWAN Network Server Demonstration: Gateway to Server Interface Definition] (https://www.thethingsnetwork.org/forum/uploads/default/original/1X/4fbda86583605f4aa24dcedaab874ca5a1572825.pdf):

**5.2.3 PULL_DATA message**

The PULL_DATA messages are periodically transmitted to the LoRa network server in order to inform the server of the UDP port number to which the network server should send any PULL_RESP message.

The PULL_DATA message also keeps open any firewall that protects the LoRa gateway.

And:

@kersing

The PULL packets use one UDP ‘connection’ and the PUSH (data and statistics) use another. Both ‘connections’ have their own originating ports and the back-end replies to the port associated with the connection.

So I’m indeed curious what you’re experiencing tomorrow.
