View source for IPv6: Router Ubuntu

[[File:IPv6-router-ubuntu.jpeg|center|300px|thumb]]

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


==Akses ke IPv6 Internet==

* [[IPv6: teredo]]
* [[IPv6: 6project.org]]
* [[IPv6: TunnelBroker Hurricane Electric]]

==Perhitungan Subnet IPv6==

* [[IPv6 Address : Perhitungan subnetting 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 sixxs -s fec0::/64 -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 sixxs -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 sixxs -p tcp --dport 8080 -j DNAT --to-destination [fec0::1234]:80

==Siapkan OS Ubuntu==

===Skenario 1: Alokasi Stateless untuk LAN lokal===

'''GATEWAY'''

Install radvd

 sudo aptitude install radvd
 echo 1 > /proc/sys/net/ipv6/conf/all/forwarding 

 interface enp3s0 {
         AdvSendAdvert on;
         prefix 2a07:1c44:0212:c0ca:87e8::/80 {
         };
 };

Restart

 /etc/init.d/radvd restart


* Aktifkan IPv6 Address Forwarding
* Aktifkan Router Advertisement

===Skenario 2: Routing Statik untuk LAN Lokal===

'''GATEWAY'''

Kondisi Gateway

 echo 1 > /proc/sys/net/ipv6/conf/all/forwarding

* Interface tun0 IPv4 10.8.0.21/24 dan IPv6 2a07:1c44:212:c0ca:87e8::/80

 echo 1 > /proc/sys/net/ipv6/conf/tun0/forwarding
 ip route add ::/0 dev tun0

* Interface enp3s0

 echo 1 > /proc/sys/net/ipv6/conf/enp3s0/forwarding
 ip addr add 2a07:1c44:212:c0ca:87e8:1000::1/84 dev enp3s0
 ip -6 route add 2a07:1c44:212:c0ca:87e8:2000::/84 via 2a07:1c44:212:c0ca:87e8:1000::100


'''CLIENT di VirtualBox'''

* Set IPv6 Static (enp0s3)

 echo 0 > /proc/sys/net/ipv6/conf/all/forwarding
 ip addr add 2a07:1c44:212:c0ca:87e8:1000::100/84 dev enp0s3
 ip addr add 2a07:1c44:212:c0ca:87e8:2000::100/84 dev enp0s3
 ip -6 route add 2a07:1c44:212:c0ca:87e8::/84 enp0s3
 ip -6 route add 2a07:1c44:212:c0ca:87e8::/84 via 2a07:1c44:212:c0ca:87e8::2/84
 ip -6 route add ::/0 via 2a07:1c44:212:c0ca:87e8::2/84

atau eth0

 echo 0 > /proc/sys/net/ipv6/conf/all/forwarding
 ip addr add 2a07:1c44:212:c0ca:87e8:1000::100/84 dev eth0
 ip addr add 2a07:1c44:212:c0ca:87e8:2000::100/84 dev eth0
 ip -6 route add 2a07:1c44:212:c0ca:87e8::/84 eth0
 ip -6 route add 2a07:1c44:212:c0ca:87e8::/84 via 2a07:1c44:212:c0ca:87e8::2/84
 ip -6 route add ::/0 via 2a07:1c44:212:c0ca:87e8::2/84

===Skenario 3: Alokasi subnet untuk salah satu PC / Router di LAN===

* Aktifkan IPv6 Address Forwarding
* Set IPv6 Static
