Cara membuat IPv6 only VPS dengan memakai Dedicated Server dari Online.net

Erawan

11 years ago

Beberapa hari ini saya ingin membuat sebuah tutorial sederhana mengenai cara pembuatan OpenVZ VPS dengan memakai Dedicated Server dari Online.net. Online.net memberikan penawaran Dedicated Server dengan harga murah, yang mungkin cukup untuk keperluan pribadi. Contohnya, kali ini saya membuat tutorial ini pada Dedibox SC Gen2 dari Online.net dengan spesifikasi berikut :

Ram 2 GB
Disk Space 500 GB
1 X Nano U2250 @ 1.6GHz
Unmetered 150Mbits/s
1 IPv4 and /48 block IPv6 ( IPv6 tidak terpakai, karena ada kesulitan dalam konfigurasinya )
€ 9.99/month atau sekitar Rp. 150.000

Pertama, kita install Dedibox SC Gen2 kita dengan pilihan Virtualization Proxmox VE2. Silakan disesuaikan setingan partisinya, kemudian dimasukkan username dan password yang diinginkan, lalu ikuti proses instalasi sampai selesai. Kadang bisa memerlukan waktu sampai satu jam, agar proses benar-benar selesai. Dan nanti kita bisa lihat URL untuk konfigurasi Proxmox kita.

Konfigurasi file resolv.conf
Silakan merubah file /etc/resolv.conf dengan baris berikut :

nameserver 8.8.8.8
nameserver 8.8.4.4
nameserver 2001:4860:4860::8888
nameserver 2001:4860:4860::8844

nameserver 8.8.8.8

nameserver 8.8.4.4

nameserver 2001:4860:4860::8888

nameserver 2001:4860:4860::8844

Konfigurasi file sysctl.conf
Silakan merubah file /etc/sysctl.conf dengan contoh berikut :

#
# /etc/sysctl.conf - Configuration file for setting system variables
# See /etc/sysctl.d/ for additonal system variables
# See sysctl.conf (5) for information.

# Uncomment the following to stop low-level messages on console
#kernel.printk = 3 4 1 3

Konfigurasi network
Karena saya memakai Tunnel IPv6 dari HE, maka jika belum memiliki account di Tunnelbroker.net, silakan mendaftar terlebih dahulu.

Penjelasan bagian he-ipv6 :

Endpoint : silakan diisi sesuai Server IPv4 Address yang tertera di Tunnelbroker
Address : silakan diisi dengan Client IPv6 Address yang tertera di Tunnelbroker, tanpa memakai /64
Netmask : silakan diisi dengan 64
Pada dua baris dibawahnya, silakan mempergunakan alamat Routed /64 dari Tunnelbroker
Selanjutnya kita mempergunakan proxy, agar IPv6 yang kita berikan ke Container dilewatkan melalui network card

Periapan Module yang diperlukan
Silakan menambahkan baris module yang diperlukan di /etc/modules.conf dengan baris berikut :

#
modprobe tun
modprobe dm_crypt
modprobe ppp-compress-18
modprobe ppp_mppe
modprobe ppp_deflate
modprobe ppp_async

Selanjutnya, silakan restart Dedicated Servernya, dan buatlah Container pertama Anda 🙂
Untuk seting DNS, silakan diisi seperti berikut :

8.8.8.8 8.8.4.4 2001:4860:4860::8888 2001:4860:4860::8844

1	8.8.8.8 8.8.4.4 2001:4860:4860::8888 2001:4860:4860::8844

Karena Dedibox SC Gen2 hanya memiliki 1 IPv4 secara default, maka agar kita bisa mengakses masing-masing Container/OpenVZ VPS yang kita buat, kita memerlukan portforwarding.
Misalnya vm100 kita memiliki IPv4 192.168.1.100, maka berikut adalah contoh agar ketika kita ingin connect ke SSH melalui Port Host akan dilewatkan ke port 22 di Container :

iptables -t nat -A PREROUTING -i vmbr0 -p tcp -m tcp --dport 10022 -j DNAT --to-destination 192.168.1.100:22

1	iptables -t nat -A PREROUTING -i vmbr0 -p tcp -m tcp --dport 10022 -j DNAT --to-destination 192.168.1.100:22

Silakan menyesuaikan keperluan port foward dengan yang diinginkan.

Saat ini, Container tidak memiliki akses ke internet sehingga perlu dilakukan portforward dari vm ke network card host :

iptables -t nat -A POSTROUTING -o vmbr0 -j SNAT --to ip.address.dedicated

1	iptables -t nat -A POSTROUTING -o vmbr0 -j SNAT --to ip.address.dedicated

Silakan disesuaikan antara vmbr atau eth0 yang mau dipakai.

Menyimpan iptables :

iptables-save > /etc/iptables.conf
nano /etc/network/if-pre-up.d/iptables

1 2	iptables-save > /etc/iptables.conf nano /etc/network/if-pre-up.d/iptables

Berikut adalah isi dari /etc/network/if-pre-up.d/iptables :

#!/bin/sh
iptables-restore < /etc/iptables.conf

1 2	#!/bin/sh iptables-restore < /etc/iptables.conf

Seting chmodnya :

chmod +x /etc/network/if-pre-up.d/iptables

1	chmod +x /etc/network/if-pre-up.d/iptables

Menambahkan IPv6 ke Container

vzctl stop 100
vzctl set 100 --ipadd 2001:470:1f12:254::2 --save
Disini container memiliki ID 100, silakan disesuaikan dengan ID Container Anda

vzctl stop 100

vzctl set 100 --ipadd 2001:470:1f12:254::2 --save

Disini container memiliki ID 100, silakan disesuaikan dengan ID Container Anda

Selanjutnya silakan login ke Container/OpenVZ vpsnya dan dicoba koneksi internet dari dalam Container/VPS 🙂
Jika berhasil, maka Anda tinggal membuat Container lain dan menambahkan IPv6 secara manual

Setting Tun/Tap
Sebelum melakukan perintah berikut, silakan distop Containernya :

vzctl stop VEID

1	vzctl stop VEID

Seting tun/tap di Containernya :

CTID=101
vzctl set $CTID --devnodes net/tun:rw --save
vzctl set $CTID --devices c:10:200:rw --save
Matikan Container terlebih dahulu
vzctl set $CTID --capability net_admin:on --save
Nyalakan Container
vzctl exec $CTID mkdir -p /dev/net
vzctl exec $CTID mknod /dev/net/tun c 10 200
vzctl exec $CTID chmod 600 /dev/net/tun

CTID=101

vzctl set $CTID --devnodes net/tun:rw --save

vzctl set $CTID --devices c:10:200:rw --save

Matikan Container terlebih dahulu

vzctl set $CTID --capability net_admin:on --save

Nyalakan Container

vzctl exec $CTID mkdir -p /dev/net

vzctl exec $CTID mknod /dev/net/tun c 10 200

vzctl exec $CTID chmod 600 /dev/net/tun

Setelah itu, silakan direstart containernya, dan berikut adalah contoh file konfigurasi untuk server openvpn atau /etc/openvpn/openvpn.conf :

local 192.xxx.xxx.xxx <-- ip lokal dari container
port 1194
proto udp
dev tun
tun-mtu 1500
tun-mtu-extra 32
mssfix 1450

Berikut adalah contoh file konfigurasi untuk Client atau client.ovpn :

client

remote 195.154.xxx.xxx 10094 <-- ip ini adalah ip dari host, dan portnya adalah port yang diforward ke port vpn container
resolv-retry infinite
nobind
tun-mtu 1500
tun-mtu-extra 32
mssfix 1450
persist-key
persist-tun
ca ca.crt

comp-lzo
verb 3

client

dev tun

proto udp #- protocol

remote 195.154.xxx.xxx 10094 <-- ip ini adalah ip dari host, dan portnya adalah port yang diforward ke port vpn container

Berikut adalah contoh port fowarding di Host :

iptables -t nat -A PREROUTING -i vmbr0 -p udp -m udp --dport 10094 -j DNAT --to-destination 192.168.1.100:1194

1	iptables -t nat -A PREROUTING -i vmbr0 -p udp -m udp --dport 10094 -j DNAT --to-destination 192.168.1.100:1194

Berikut adalah setingan iptables di Container :

iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -j SNAT --to 192.168.1.100

1	iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -j SNAT --to 192.168.1.100

Jadi singkatnya, permintaan koneksi vpn dari komputer atau client ke container akan dilewatkan dari port 10094 Host ke port 1194 Container.
