OSMOCOM TRX_BTS_BSC Connection Issue

[Aalto Koskinen]

Hi Vadim,

Thank you for your quick replies. (Previously, due to error, I sent reply
to you. Now, I have resent with openbsc in cc)

I wasn't sure, if my firewall is blocking the port or not. Hence, I took a
wire shark trace test.pcap. I ran sudo ufw allow 5701 and sudo ufw allow
5801 and then again took wire shark trace test2.pcap. Both traces are
attached. From my inspection, the ports have still the same messages.

I am also attaching the configuration of other components, as a reference.

Thanks again for the help
