==5G Core==

kalau install dari binary cd ke folder

cd /etc/open5gs
cp amf.yaml amf.yaml.old
vi amf.yaml

Pastikan

amf:

# - addr: 127.0.0.5
- addr: 10.10.0.5

Modify /etc/open5gs/upf.yaml untuk set GTP-U dan PFCP IP address.

cd /etc/open5gs
cp upf.yaml upf.yaml.old
vi upf.yaml

Pastikan

upf:
pfcp:
- addr: 127.0.0.7
gtpu:
# - addr: 127.0.0.7
- addr: 10.11.0.7
subnet:
- addr: 10.45.0.1/16
- addr: 2001:db8:cafe::1/48
metrics:
- addr: 127.0.0.7
port: 9090

Restart Open5GS,

sudo systemctl restart open5gs-amfd
sudo systemctl restart open5gs-upfd

==4G/ 5G NSA Core==

Modify /etc/open5gs/mme.yaml untuk set S1AP IP address, PLMN ID, dan TAC.

cd /etc/open5gs
cp mme.yaml mme.yaml.old
vi mme.yaml

Pastikan

mme:
freeDiameter: /etc/freeDiameter/mme.conf
s1ap:
# - addr: 127.0.0.2
- addr: 10.10.0.2
gtpc:
- addr: 127.0.0.2
metrics:

mnc: 70
tac: 1
security:
integrity_order : [ EIA2, EIA1, EIA0 ]
ciphering_order : [ EEA0, EEA1, EEA2 ]
network_name:
full: Open5GS

Modify /etc/open5gs/sgwu.yaml untuk set GTP-U IP address.

cd /etc/open5gs
cp sgwu.yaml sgwu.yaml.old
vi sgwu.yaml

Pastikan,

sgwu:
pfcp:
- addr: 127.0.0.6
gtpu:
# - addr: 127.0.0.6
- addr: 10.11.0.6

Restart,

sudo systemctl restart open5gs-mmed
sudo systemctl restart open5gs-sgwud

Jika kita compile open5gs, kemungkinan script untuk systemctl belum ada. Ini akan menimbulkan ERROR.

==Setup TUN device (not persistent)==

Jika dibutuhkan kita dapat menset interface ogstun, tampaknya ini tidak dibutuhkan jika kita menginstall open5gs dari binary.

Untuk membuat TUN device dengan nama interface ogstun, caranya adalah sebagai berikut,

sudo ip tuntap add name ogstun mode tun
sudo ip addr add 10.45.0.1/16 dev ogstun
sudo ip addr add 2001:db8:cafe::1/48 dev ogstun
sudo ip link set ogstun up

Tip: script ini tersedia di $GIT_REPO/misc/netconf.sh yang akan memudahkan kita dapat mengkonfigurasi TUN device:

sudo ./misc/netconf.sh

==Tambahkan Route Untuk UE ke WAN / Internet==

Agar ada bridge antara PGWU/UPF dan WAN (Internet), kita perlu meng-enable IP forwarding dan NAT rule di IP Tables.

Untuk mengaktifkan forwarding dan NAT rule, ketik,

### Enable IPv4/IPv6 Forwarding
sudo sysctl -w net.ipv4.ip_forward=1
sudo sysctl -w net.ipv6.conf.all.forwarding=1

### Add NAT Rule
sudo iptables -t nat -A POSTROUTING -s 10.45.0.0/16 ! -o ogstun -j MASQUERADE
sudo ip6tables -t nat -A POSTROUTING -s 2001:db8:cafe::/48 ! -o ogstun -j MASQUERADE

Cek menggunakan perintah,

iptables -L -t nat

Hasilnya harusnya NAT beroperasi seperti dibawah ini,

Chain POSTROUTING (policy ACCEPT)
target prot opt source destination
MASQUERADE all -- 10.45.0.0/16 anywhere

Konfigurasi firewall dengan benar dan pastikan status ufw inactive.

sudo ufw status

Status: active

Jika dibutuhkan, firewall dapat dimatikan menggunakan perintah berikut, dan disable waktu start up,

sudo ufw disable

Matikan firewall dan disable pada system startup

$ sudo ufw status

Status: inactive

Optional, jika dibutuhkan, kita dapat melakukan konfigurasi berikut,

### Ensure that the packets in the `INPUT` chain to the `ogstun` interface are accepted
$ sudo iptables -I INPUT -i ogstun -j ACCEPT

### Prevent UE's from connecting to the host on which UPF is running
$ sudo iptables -I INPUT -s 10.45.0.0/16 -j DROP
$ sudo ip6tables -I INPUT -s 2001:db8:cafe::/48 -j DROP

### If your core network runs over multiple hosts, you probably want to block
### UE originating traffic from accessing other network functions.
### Replace x.x.x.x/y with the VNFs IP/subnet
$ sudo iptables -I FORWARD -s 10.45.0.0/16 -d x.x.x.x/y -j DROP
