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 18.104.22.168 for the first UE and 22.214.171.124 for the second. Then on the EPC machine, do: ping 126.96.36.199 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.
