You received a IPACC CRCX NACK from nanoBTS as an answer to IPACC_CRCX
(that's sent osmoBSc->nanoBTS to configure the RTP stream on the nanoBTS
side).
So it seems the nanoBTS is not liking the configuration you are
requesting to it?
Providing a pcap file containing Abis RSL would help understand better
by looking at what the IPACC CRCX contains.
I'd bet you are passing a loopback address to it or something similar,
probably due to wrong osmo-mgw configuration.
