For more information, see Elastic IP Addresses in the Amazon EC2 User Guide for Linux Instances. This public IP serves as an access point to the admin web interface and a tunnel establishment endpoint for VPN clients. Associating an Elastic IP addressĪfter your EC2 instance is running, it’s a best practice to associate an Elastic IP address so that you can remap the same address to another instance in case the current instance fails. At the same time, the OpenVPN daemon listening on port 443 can handle incoming tunnel connections, thus bypassing any existing firewall limitation. Thanks to this OpenVPN protocol feature called port sharing, any incoming HTTPS connection on port 443 is automatically remapped to the actual web service running on port 943. To enable OpenVPN to work well in that situation, by default the OpenVPN daemon listens on the TCP port 443 and can forward incoming web browser requests to a web service on port TCP 943 (since you cannot have both the web server and the OpenVPN server listening on the same port). Sometimes, firewalls on public networks block everything except the most common ports, such as HTTP (TCP/80) and HTTPS (TCP/443). You might wonder why you should open port TCP/943.
The following image shows this configuration. You might notice that in the security group settings, OpenVPN Access Server requires you to allow inbound traffic for TCP/22 (SSH), TCP/943, TCP/443 (HTTPS access to web interface), and UDP/1194 ( IANA reserved port for OpenVPN protocol). This key is installed on the EC2 instance, allowing you to have SSH access.
