Handling EU868 and US915 same time

I have loraserver that works fine with EU868 devices.
Trying to handle US915 devices via separate gateway gives me following packet-forwarder log:

So I checked global_conf.json (it was taken from TTN’s github) and saw following:

"tx_freq_min": 923000000,
"tx_freq_max": 928000000

After changing tx_freq_min to 902000000 the error is gone but JOIN procedure doesn’t occure. I think there is because loraserver tries to TX on 904300000.

Joining with TTN works fine with following logs:

Searching on forum found this topic:

Changing [network_server.band] to US_902_928 and restarting loraserver service maid successful JOIN procedure.
Now I want to handle EU868 and US915 end nodes same time using loraserver.
I have loraserver, lora-app-server and other services running in docker containers. Does it possible to run two loraserver services (one for EU868 and second for US915) both communicating with same lora-app-server with pointing EU868 gateways to port 1700 and US915 to port 1701 for example?

You cannot. You must set up one loraserver per region/band.

Yes, one lora-app-server to two loraservers would work fine. You would want to run two gateway bridges on different ports (or different IPs), as you’ve noted.
