Hi @free5GC and everyone,
Could you pls help on my below issue.
When I do pdu session, looks like registration is successful (UE got IP), but there is an error on SMF handling NGAP ‘PDUSessionResourceSetupResponse’ message, as highlighted below.
NGAP log:
Here is my setup:
free5gc (including UPF) IP: 192.168.5.60
UE (gnbsim): 192.168.5.72
I also have a web server *172.16.1.2) connected to free5gc, as below
‘sudo ufw allow from any to 172.16.1.2 port 8080 proto tcp’ successfully ran on web server
on free5gc server, successful run ‘sudo ufw allow from 172.16.1.2 to any port 8080 proto tcp’
on free5gc side, I can open this page ‘http:172.16.1.2’
on the web server, below is successfully:
sudo ip route add 60.60.0.0/24 via 172.16.1.1
gnbsim (UE side log): (although it says ‘failed to GET http://172.16.1.2:8080/’, I guess the issue is on the NGAP message 'PDUSessionResourceSetupResponse, as this message is not received on gnbsim ue side
