SRSRAN Network Model

[Cabochards]

Hello guys !

I am a total SRSran newbie and I wanted to do a little project for school. Here is the model that I want to build :

I initialize my SRSran 4G core like that all in local without USRP

sudo ip netns add ue1

Step 1: Start the EPC (Evolved Packet Core)
From the directory ~/srsRAN_4G/build/srsepc, run:
sudo ./src/srsepc

Step 2: Start the eNodeB
From the directory ~/srsRAN_4G/build/srsenb, run:
sudo ./src/srsenb --rf.device_name=zmq --rf.device_args="fail_on_disconnect=true,tx_port=tcp://*:2000,rx_port=tcp://localhost:2001,id=enb,base_srate=23.04e6"

Step 3: Start the UE (User Equipment)
From the directory ~/srsRAN_4G/build/srsue, run:
sudo ./src/srsue --rf.device_name=zmq --rf.device_args="tx_port=tcp://*:2001,rx_port=tcp://localhost:2000,id=ue,base_srate=23.04e6" --gw.netns=ue1 --log.filename=stdout

I manage to ping the SPGW/UE while being in CLI1/2

But as far as I am it doesnt seems to work. Problem is that I try to ping CLI1 <-> CLI2 going through the 4G core but it doesnt seems to work, my ICMP paquets always do enp0s3 <-> enpos8 and never manage to go in the 4G network. I have tried many things changing the ip route in all my vms, blocking my physical network card by doing an iptables and forcing all type of packet to go in the srs_spgw_sgi route and putting all my physical card in the netns ue1 space and always tried to change epc.conf but as far as I know it doesnt seems to work. I kinda need your help and seeking advice. TY a lot

For context here is my configuration in the VM2

Here the ping in my CLI 1

So far with all that some part of this model is working some not well so rn I am stuck ¯_(ツ)_/¯.
