There seems to be an issue with IP-SNS NSVCs that never come up:

OsmoGbProxy# show ns             
NSEI 00004: UDP, DEAD
 FSM Instance Name: 'GPRS-NS2-SNS-BSS(NSE00004-SNS)[0x55bfd8ffbf10]', ID: 'NSE00004-SNS'
  Log-Level: 'DEBUG', State: 'CONFIGURED'
 Maximum number of remote  NS-VCs: 8, IPv4 Endpoints: 4, IPv6 Endpoints: 0
 Local IPv4 Endpoints:
  10.0.0.1:2157, Signalling Weight: 2, Data Weight: 1
 Remote IPv4 Endpoints:
  10.0.0.2:43072, Signalling Weight: 1, Data Weight: 0
  10.0.0.2.168:2158, Signalling Weight: 0, Data Weight: 1
 NSVCI none: ALIVE DYNAMIC data_weight=1 sig_weight=0 udp)[10.0.0.1]:2157<>[10.0.0.2]:2158
 NSVCI none: ALIVE DYNAMIC data_weight=0 sig_weight=1 udp)[10.0.0.1]:2157<>[10.0.0.2]:43072
 NSVCI none: UNCONFIGURED DYNAMIC data_weight=1 sig_weight=1 udp)[10.0.0.1]:2157<>[10.0.0.2]:2157

Here remote port 2157 was configured in osmo-gbproxy, but all packets are dropped. According to lynxis we should never be in the state UNCONFIGURED for an NSVC.
