ue_ip: use correct instance
The problem was the following. Run oaisim with two UEs: sudo ../cmake_targets/oaisim_build_oai/build/oaisim -O enb.conf -u2 -s15 -AAWGN -y1 -b1 -Q0 Then wait for both UEs to be connected. The interfaces "oip1" and "oip2" are activated, with IP addresses 220.127.116.11 for the first UE and 18.104.22.168 for the second. Then on the EPC machine, do: ping 22.214.171.124 No reply. On the oaisim machine, we see that the packets are sent to "oip1" instead of "oip2". The fix may break softmodem UE. The inst was forced to "1" for some reason. To be checked.
