Фух, ну наконец-то мучения с настройкой vpn закончено.
Скажем так - статьи аля тыц и тыц не взлетели.
Разница возможно в том что там описан VPN Amazon, а не для DigitalOcean. Хз что там не так. Возможно это просто у меня кривые руки.
Статейку нашел, вкурил (но пока не до конца разобрался с iptables)
Вот оригинал тыц

копия для себя, щоб не пропало

Step 1 - PPTP Installation
You will have to select one server to be responsible for handling out IPs to others and authenticating all of your servers into your VPN. 
This will become your PPTP Server.

On Ubuntu 12.10 x64:
apt-get install pptpd

Now you should edit /etc/pptpd.conf and add the following lines:
localip 10.0.0.1
remoteip 10.0.0.100-200

Where localip is IP address of your server and remoteip are IPs that will be assigned to clients that connect to it.
Next, you should setup authentication for PPTP by adding users and passwords. Simply add them to /etc/ppp/chap-secrets :

Where client is the username, server is type of service – pptpd for our example, secret is the password, and IP addresses specifies which IP address may authenticate.
By setting ‘*’ in IP addresses field, you specify that you would accept username/password pair for any IP.

Step 2 - Add DNS servers to /etc/ppp/pptpd-options
ms-dns 8.8.8.8
ms-dns 8.8.4.4

Now you can start PPTP daemon:
service pptpd restart

Verify that it is running and accepting connections:

Step 3 - Setup Forwarding
It is important to enable IP forwarding on your PPTP server. This will allow you to forward packets between public IP and private IPs that you setup with PPTP.
Simply edit /etc/sysctl.conf and add the following line if it doesn’t exist there already:
net.ipv4.ip_forward = 1

To make changes active, run sysctl -p
Step 4 - Create a NAT rule for iptables
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE && iptables-save

If you would also like your PPTP clients to talk to each other, add the following iptables rules:

iptables --table nat --append POSTROUTING --out-interface ppp0 -j MASQUERADE
iptables -I INPUT -s 10.0.0.0/8 -i ppp0 -j ACCEPT
iptables --append FORWARD --in-interface eth0 -j ACCEPT

Now your PPTP server also acts as a router. 

Вообщем, если чо - могу дать ключи для доступа по впн. (Удобная штука чтобы получить доступ на американ. ресурсы аля music.twitter.com/)
А то хз что там еще они (политики) намутят - авось потом вообще инет заблочат и будет как в том посте по Поисковик РФ.
