NAT Port Forwarding

In order to bridge between the 5G Core UPF and Internet, we need enable IP forwarding and add a NAT rule to the IP Tables. Following are the NAT port forwarding we have to do. Without this port forwarding the connectivity from 5G Core to internet would not work.

sudo sysctl -w net.ipv4.ip_forward=1
sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
sudo systemctl stop ufw
sudo iptables -I FORWARD 1 -j ACCEPT
