Hi!
I am following the installation in free5gc-compose github page and connected it to the UERANSIM. The docker-compose version of free5gc and UERANSIM are installed in the same PC. The free5gc-compose did not have any error and PDU session is established successfully, but I cannot ping google dot com using uesimtun0 interface.
After running ‘sudo docker-compose up’ and before I start UERANSIM, I also enter the following in my host PC
sudo sysctl -w net.ipv4.ip_forward=1
sudo iptables -t nat -A POSTROUTING -o ens18 -j MASQUERADE
sudo systemctl stop ufw
sudo iptables -I FORWARD 1 -j ACCEPT
But still, I cannot ping google dot com using “ping -I uesimtun0 google dot com”. I attach pcap file of (possibly) N3 or N6 interface and uesimtun0 (new user can only put two links). But basically, they only have ICMP request but no response.
Does anyone know what is happening and how can I solve this? Thank you very much!!!
