IPv6-router-ubuntu.jpeg

Berikut adalah langkah yang perlu dilakukan untuk membuat sebuah router IPv6 sederhana menggunakan Ubuntu.


Akses ke IPv6 Internet

Perhitungan Subnet IPv6


NAT IPv6

Jika dibutuhkan, maka netfilter6 dapat digunakan sebagai NAT IPv6.

IPv6 Masquerading

Seperti layaknya client IPv4, maka client dapat di sembunyikan di belakang router dengan IPv6 masquerading (hide/overlap NAT), seperti 

ip6tables -t nat -A POSTROUTING -o tun0 -s fec0::/64 -j MASQUERADE
ip6tables -t nat -A POSTROUTING -o teredo -s 2001:0:53aa:64c:20a7:659c:4b0c:e8d7 -j MASQUERADE

IPv6 Destination NAT

Sebuah dedicated IPv6 address global dapat di forward ke internal IPv6 address, seperti, 

ip6tables -t nat -A PREROUTING -d 2001:db8:0:1:5054:ff:fe01:2345 -i tun0 -j DNAT --to-destination fec0::5054:ff:fe01:2345

IPv6 Port Forwarding

Sebuah port yang spesifik dapat di forward ke jaringan internal, seperti, 

ip6tables -t nat -A PREROUTING -i tun0 -p tcp --dport 8080 -j DNAT --to-destination [fec0::1234]:80

Siapkan OS Ubuntu

Skenario 1: teredo dan Alokasi Stateless untuk LAN lokal

Topology 

Client --- e1-SERVER-e0 --- Internet


GATEWAY / Router ke Internet

Install teredo 

sudo su
apt install miredo
/etc/init.d/miredo restart

Install radvd 

echo 1 > /proc/sys/net/ipv6/conf/all/forwarding 
echo 1 > /proc/sys/net/ipv6/conf/default/forwarding 
echo 1 > /proc/sys/net/ipv6/conf/enp0s3/forwarding
echo 1 > /proc/sys/net/ipv6/conf/enp0s8/forwarding
echo 1 > /proc/sys/net/ipv6/conf/teredo/forwarding 

ip addr add fec0:1234::dead/64 dev enp0s8
ifconfig enp0s8 up
sudo apt install radvd

Edit /etc/radvd.conf 

interface enp0s8 {
        AdvSendAdvert on;
        prefix fec0:1234::/64 {
        };
};

Restart 

/etc/init.d/radvd restart

NAT ke IPv6 Global 

ip6tables -t nat -A POSTROUTING -o teredo -s fec0:1234::/64 -j MASQUERADE


CLIENT

  • interface menggunakan IPv6 automatic; IPv4 bisa di matikan.
  • edit /etc/resolv.conf
# nameserver Google IPv6
nameserver 2001:4860:4860::8888
nameserver 2001:4860:4860::8844

Skenario 2: 6project dan IPv6 Static LAN lokal

Topology 

Client --- e1-SERVER-e0 --- Internet

Alokasi IPv6 dari 6project.org hanya /80, hanya bisa untuk static LAN saja. Tidak bisa untuk yang lain.


GATEWAY / Router ke Internet 

sudo su
apt update
apt install openvpn
openvpn --config usernameanda-di-6project.ovpn &

echo 1 > /proc/sys/net/ipv6/conf/all/forwarding 
echo 1 > /proc/sys/net/ipv6/conf/default/forwarding 
echo 1 > /proc/sys/net/ipv6/conf/enp0s3/forwarding
echo 1 > /proc/sys/net/ipv6/conf/enp0s8/forwarding
echo 1 > /proc/sys/net/ipv6/conf/tun0/forwarding 

ip addr del 2a07:1c44:212:c0ca:87e8::/80 dev tun0
ip addr add 2a07:1c44:212:c0ca:87e8:8000::1/81 dev tun0
ip addr add 2a07:1c44:212:c0ca:87e8:0000::dead/81 dev enp0s8
ifconfig enp0s8 up
ip route add ::/0 dev tun0


Flush firewall 

ip6tables -t nat -F
ip6tables -F

CLIENT

Supaya mudah sebaiknya setup client dilakukan menggunakan fasilitas konfigurasi jaringan yang GUI. Untuk client yang CLI dapat menggunakan perintah di bawah ini, 

ip addr add 2a07:1c44:212:c0ca:87e8:0000::123/81 dev eth0
ip route add ::/0 via 2a07:1c44:212:c0ca:87e8:0000::dead

atau 

ip route add ::/0 dev enp0s3


Edit /etc/resolv.conf 

# nameserver Google IPv6
nameserver 2001:4860:4860::8888
nameserver 2001:4860:4860::8844


Cek 

dig aaaa ipv6.google.com
ping6 ipv6.google.com

Skenario 3: 6project alokasikan DHCPv6 LAN + ndp

Disini alokasi IPv6 dari 6project di alokasikan menggunakan DHCPv6. Tapi routing, proxy ndp semua harus di set manual supaya jalan. Sebetulnya mirip dengan static routing saja, tapi alokasi IPv6 via DHCPv6.


GATEWAY

Aktifkan neighbor discovery proxy (ndp) 

echo 1 > /proc/sys/net/ipv6/conf/all/proxy_ndp
echo 1 > /proc/sys/net/ipv6/conf/tun0/proxy_ndp
echo 1 > /proc/sys/net/ipv6/conf/all/forwarding
echo 1 > /proc/sys/net/ipv6/conf/default/forwarding
echo 1 > /proc/sys/net/ipv6/conf/tun0/forwarding
echo 1 > /proc/sys/net/ipv6/conf/enp0s3/forwarding

Lakukan proxy ke masing2 IPv6 client, misalnya 

openvpn --config XXXX.ovpn
ip addr del 2a07:1c44:212:c0ca:87e8::/80 dev tun0
ip addr add 2a07:1c44:212:c0ca:87e8:8000::1/81 dev tun0
ip addr add 2a07:1c44:212:c0ca:87e8::1/81 dev enp0s3
ip route add ::/0 dev tun0
ip route add 2a07:1c44:212:c0ca:87e8::/81 enp0s3

ip -6 neigh add proxy 2a07:1c44:212:c0ca:87e8::22 dev tun0

CLIENT

PROBLEM Skenario: 6project alokasikan DHCPv6 LAN

CATATAN:

  • DHCPv6 tampaknya hanya bisa mengalokasikan /128 harus di bantu RA utk < /128.
  • Routing tidak di set
  • RA juga tidak berfungsi untuk alokasi < /64, tadi harus di routing di konfigurasi manual.

DHCPv6 server 

apt install isc-dhcp-server

Edit /etc/dhcp/dhcpd6.conf

Aktifkan radvd 

sudo apt install radvd

Edit /etc/radvd.conf 

interface enp0s3 {
        AdvSendAdvert on;
        prefix 2a07:1c44:212:c0ca:87e8::/81 {

Flush firewall 

ip6tables -t nat -F
ip6tables -F

PROBELM Skenario: 6Project dan Alokasi Stateless untuk LAN lokal

CATATAN:

  • 6project.org hanya mengalokasikan /80
  • /80 tidak bisa dipakai untuk Stateless menggunakan radvd
  • radvd aman untuk alokasi /64 atau lebh besar.
