i have installed the things stack 3.7.1 on a debian vm.
my mikrotik test gateway forwards all data to ttn and my vm.
now to the problem:
all data is received by ttn but my vm with the things stack only is receiving packets on channel index 1 and 2. my vm and the gateway are on the same subnet so no internet between.
if i switch my local vm to a vm with chirpstack installed, chirpstack is receiving all packets like ttn.
the gateways and nodes are in the EU868 frequency plan
