Are you using mLinux or AEP? What version?
Is this a setup you had working at one point and now it is not working?
Can you elaborate on the network problem causing the LoRa AP to stop?
The network server requires a packet forwarder to send packets from the radio hardware. A packet forwarder process should be started by the network server init script.
Can you check the packet forwarder process on the LoRa GW?
# ps -A | grep lora
Or try to start manually to see if there are error?
# cd /var/run/lora/1
# ./lora_pkt_fwd
For the network server to receive from the remote gateway the firewall must be opened and the network server configured to listen on the public ethernet interface. The “udp” > “allowPublic” setting must be set true.
