I try to integrate a RAK 7249 in our existing Chirpstack Environment.
By now I have Gateways based on RPi + RAK2245 that communicate using UDP Packet forwarder via OpenVPN.
Now I wanted to add a RAK7249 because I need the LTE connection.
I setup LTE and OpenVPN which looks to work properly bebecause I can contact the web GUI over VPN connection and I can ping the chirpstack components from within the web GUI.
In the systemlog I can see that lora_pkt_fwd is working and sending up messages as well as the received datagrams.
Neither the up messages nor the datagrams are received on chirpstack side.
So every 30 datagrams the lora_pkt_fwd restarts.
Firmware Version is: 1.1.0062_Release r202
Here is the VPN config (which works fine on the RPi s) :
client nobind dev tun remote-cert-tls server remote vpn.mydomain.com 1194 udp4 <key> -----BEGIN PRIVATE KEY----- .... -----END PRIVATE KEY----- </key> <cert> -----BEGIN CERTIFICATE----- ... -----END CERTIFICATE----- </cert> <ca> -----BEGIN CERTIFICATE----- ... -----END CERTIFICATE----- </ca> key-direction 1 <tls-auth> # # 2048 bit OpenVPN static key # -----BEGIN OpenVPN Static key V1----- ... -----END OpenVPN Static key V1----- </tls-auth> redirect-gateway def1
Packet Forwarder is configured as follow:
Any idea why packets are not transferred to chirpstack?
