As we all know the benefits of using a Virtual Private Network like privacy, anonymity, security, overcoming geographical restrictions and so on. This guide will walk you through all the steps to setting your own VPN between Open Telekom Cloud and AWS cloud. 

Preparation

Deployment

Step 1: Create VPN on Open Telekom Cloud:

At beginning, we have the configuration of VPC, subnet on Open Telekom Cloud side and remote side subnet on AWS. While in this step, we do not know remote gateway of AWS and exact PSK, so just give a number, we will change it later.

Policy configuration as follows:

Configuration of VPN

Configuration of VPN

After creation, write down OPEN TELEKOM CLOUD local gateway address where, in this case, local gateway is ‘93.188.242.51’

Step 2: Create customer gateway in AWS, where IP address is the Open Telekom Cloud local gateway got from step 1

Create Customer Gateway

Step 3: Create virtual private gateway and attach to VPC

Create Virtual Private Gateway

Step 4: Create new VPN in AWS, choose gateway and virtual private gateway from step 2 and 3, then choose static router, static IP/CIDR from step 1

Create VPN Connection

Step 5: Check AWS VPN tunnel information and keep tunnel IP, in this case, will use ’52.220.197.206’ as AWS VPN gateway

Step 11: Let’s have a ping test, if everything is ok, job done!

Ping test

* If any propagated routes from a VPN connection or AWS Direct Connect connection overlap with the local route for your VPC, the local route is most preferred even if the propagated routes are more specific. 

**VPN will not work until first active traffic is sent from one side.
