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

GATEWAY / Router ke Internet

Install radvd

echo 1 > /proc/sys/net/ipv6/conf/all/forwarding 
ip addr add fec0:1234::dead/64 dev enp0s3
sudo apt install radvd

Edit /etc/radvd.conf

interface enp0s3 {
        AdvSendAdvert on;
        prefix fec0:1234::/64 {
        };
};

Restart

/etc/init.d/radvd restart

NAT ke IPv6 Global

ip6tables -t nat -A POSTROUTING -i enp3s0 -o teredo -s fec0:1234::/64 -j MASQUERADE



Skenario 2: 6project dan IPv6 Static LAN lokal

GATEWAY / Router ke Internet


openvpn --config usernameanda-di-6project.ovpn
echo 1 > /proc/sys/net/ipv6/conf/all/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 enp0s3
ip route add ::/0 dev tun0


Flush firewall

ip6tables -t nat -F
ip6tables -F

CLIENT

ip addr add 2a07:1c44:212:c0ca:87e8:0000::123/81 dev enp0s3
ip route add ::/0 via 2a07:1c44:212:c0ca:87e8:0000::dead

Cek

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

Skenario 3: 6project alokasikan seluruhnya untuk LAN

openvpn --config usernameanda-di-6project.ovpn &
echo 1 > /proc/sys/net/ipv6/conf/all/forwarding 
ip addr del 2a07:1c44:212:c0ca:87e8::/80 dev tun0
ip addr add fec0::/80 dev tun0
ip route add ::/0 dev tun0
ip addr add 2a07:1c44:212:c0ca:87e8::2/80 dev enp0s3

Edit /etc/radvd.conf

interface enp0s3 {
        AdvSendAdvert on;
        prefix 2a07:1c44:212:c0ca:87e8::/80 {
        };
};
/etc/init.d/radvd restart

Flush firewall

ip6tables -t nat -F
ip6tables -F
