Aplikasi open source untuk mengimplementasi Virtual Private Network (VPN) yang cukup populer adalah OpenVPN. OpenVPN menggunakan protocol SSL / TLS untuk mempertukarkan kunci. Pada kesempatan ini akan di terangkan cara mengaktifkan OpenVPN untuk IPv6.

Instal OpenVPN

Agar mudah kita menggunakan OpenVPN road warrior installer. Download dan jalankan script untuk instalasi menggunakan perintah

sudo su
rm /var/lib/dpkg/lock
apt update

cd /usr/local/src
wget https://git.io/vpn -O openvpn-install.sh
sudo bash openvpn-install.sh

Beberapa informasi yang dibutuhkan

IP address OpenVPN:
Public IP address / hostname:
Protocol UDP / TCP
Port: 1194 (UDP)
DNS: Google
Client name: coba1

Jika OpenVPN serve telah di konfigurasi dan siap pakai. Akan tampak di rules firewall di /etc/rc.local kira-kira

$ cat /etc/rc.local
iptables -I FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -I FORWARD -s 10.8.0.0/24 -j ACCEPT
iptables -I INPUT -p udp --dport 1194 -j ACCEPT
iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -j SNAT --to 203.0.113.10

Jalankan OpenVPN, ketik

sudo /etc/init.d/openvpn start

Sertifikat client di simpan di home directory,

coba1.ovpn

AKtifkan IPv6

Langkah selanjutnya adalah mengaktifkan IPv6.

Now let’s enable IPv6. For the configuration I am using IP 2001:db8:ee00:ee00::10/64 for the VPN server.

2001:db8:ee00:abcd::/64 has been routed to the OpenVPN server host. That mean users connected via OpenVPN will get an address from 2001:db8:ee00:abcd::/64

Step 1: We need to edit the OpenVPN configuration file and enable IPv6 tunnel service

vi /etc/openvpn/server.conf

Add the following:

server-ipv6 2001:0db8:ee00:abcd::/64 tun-ipv6 push tun-ipv6 ifconfig-ipv6 2001:0db8:ee00:abcd::1 2001:0db8:ee00:abcd::2 push "route-ipv6 2001:0db8:ee00:ee00::2/64" push "route-ipv6 2000::/3"

Step 2: Enable IPv6 forwarding:

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

Step 3: Reload OpenVPN Service

sudo /etc/init.d/openvpn restart

Try to connect your OpenVPN client.

From the Tunnelblick log you can verify the IP addresses:

Test the IPv6 reachability by accessing http://test-ipv6.com/

Note: 1. To make IPv6 forwarding persistent, remember to uncomment in /etc/sysctl.conf:

net.ipv6.conf.all.forwarding = 1

2. Make sure that you route 2001:db8:ee00:abcd::/64 to your OpenVPN Server. I have done this from my Cisco router:

ipv6 route 2001:db8:ee00:abcd::/64 2001:db8:ee00:ee00::10

So you now have native IPv6 and can access all IPv6-enabled services. As a roaming user, it will give you better security.

-That’s it. Your OpenVPN server has been configured and is ready to use. You can see the added firewall rules /etc/rc.local file:

-To connect from MacOSX, you can use TunnelBlick.
-To add a new client, run the openvpn-install.sh script. Choose option 1 to add a new client and the certificate will be stored in the home folder.

 Now let’s enable IPv6. For the configuration I am using IP 2001:db8:ee00:ee00::10/64 for the VPN server.
