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

Access Open5gs Dashboard

Now we need to access our open5gs dashboard.

sudo apt update
sudo apt install curl
curl -fsSL https://deb.nodesource.com/setup_14.x | sudo -E bash -
sudo apt install nodejs
git clone https://github.com/open5gs/open5gs.git

# run webui with npm
