OpenVPN endpoint

The lab has a virtual machine for NAT, which acts as a bridge between the internet (WAN) and the private networks within the AWS Cloud (VPCs).

NAT instance is the VPN endpoint.

OpenVPN route for Elasticsearch DB access

The .ovpn config needs to be extended for the route:

...
-----END OpenVPN Static key V1-----
</tls-auth>


# Add this line to route traffic to 192.168.20.106 through the VPN
route 192.168.20.106 255.255.255.255
