After the child sa exchange and and new terminal was created my topology:
10.0.0.8 – 192.168.86.38 === 192.168.86.39 – 10.0.0.1
60.60.0.3 – 192.168.86.38 === 192.168.86.39 – 192.168.82.5 (n3iwf gtp bind address) ------------ 127.0.0.8 (upf)
at this point, I want to ping from ue 60.60.0.3 to 192.168.82.5 but the ping is not going through.
I checked the xfrm state and policy and it had the same spi for both ways. 60.60.0.3 -> 192.168.82.5 and 192.168.82.5 --> 60.60.0.3 in free5gc, but in ue (I used strongswan) it had different spi for each ways. I think this is the many reason the ping is not working, but I am not sure. So, is the spi the same for the child sa for both way?
Hi @joseph1267,
