Static key configurations offer the simplest setup, and are ideal for point-to-point VPNs or proof-of-concept testing.
Static Key advantages
- Simple Setup
- No X509 PKI (Public Key Infrastructure) to maintain
Jun 27, 2019 How to setup and use OpenVPN Connect. Try your provider's client for one session, OpenVPN for the next, see which you like best. The site will display your new IP address and tell you. While Encrypting a File with a Password from the Command Line using OpenSSL is very useful in its own right, the real power of the OpenSSL library is its ability to support the use of public key cryptograph for encrypting or validating data in an unattended manner (where the password is not required to encrypt) is done with public keys. I was trying to set up the OpenVPN on my Untangle box last night but seemed to have a bit of trouble. My Untangle box sits between standard router and a virtual network. I want to be able to set up the VPN so that people can connect in with their machines over the internet and become part of that virtual network. Jun 29, 2017 See the easy-rsa/build-key-server script for an example of how to generate a certificate with the nsCertType field set to 'server'. If the server certificate's nsCertType field is set to 'server', then the clients can verify this with -ns-cert-type server. Jan 19, 2020 Contribute to OpenVPN/openvpn development by creating an account on GitHub. As a first step towards using the keying material exporter as a method to generate key material for the data channel, implement the -keying-material-exporter function we already have for OpenSSL also for mbed TLS builds. Allow them to just do '-genkey new.key.
Static Key disadvantages
- Limited scalability — one client, one server
- Lack of perfect forward secrecy — key compromise results in total disclosure of previous sessions
- Secret key must exist in plaintext form on each VPN peer
- Secret key must be exchanged using a pre-existing secure channel
Simple Example
This example demonstrates a bare-bones point-to-point OpenVPN configuration. A VPN tunnel will be created with a server endpoint of 10.8.0.1 and a client endpoint of 10.8.0.2. Encrypted communication between client and server will occur over UDP port 1194, the default OpenVPN port.
Generate a static key:
Copy the static key to both client and server, over a pre-existing secure channel.
Server configuration file
Client configuration file
Firewall configuration
Make sure that:
- UDP port 1194 is open on the server, and
- the virtual TUN interface used by OpenVPN is not blocked on either the client or server (on Linux, the TUN interface will probably be called tun0 while on Windows it will probably be called something like Local Area Connection n unless you rename it in the Network Connections control panel).
Bear in mind that 90% of all connection problems encountered by new OpenVPN users are firewall-related.

Testing the VPN
Run OpenVPN using the respective configuration files on both server and client, changing myremote.mydomain in the client configuration to the domain name or public IP address of the server.
To verify that the VPN is running, you should be able to ping 10.8.0.2 from the server and 10.8.0.1 from the client.
Expanding on the Simple Example
Use compression on the VPN link
Add the following line to both client and server configuration files:
Make the link more resistent to connection failures
Deal with:
- keeping a connection through a NAT router/firewall alive, and
- follow the DNS name of the server if it changes its IP address.
Add the following to both client and server configuration files:
Run OpenVPN as a daemon (Linux/BSD/Solaris/MacOSX only)
Untangle Nat Openvpn Traffic
Run OpenVPN as a daemon and drop privileges to user/group nobody.
Add to configuration file (client and/or server):
Generate Openvpn File
Allow client to reach entire server subnet
Suppose the OpenVPN server is on a subnet 192.168.4.0/24. Add the following to client configuration:
Untangle Vpn
Then on the server side, add a route to the server’s LAN gateway that routes 10.8.0.2 to the OpenVPN server machine (only necessary if the OpenVPN server machine is not also the gateway for the server-side LAN). Also, don’t forget to enable IP Forwarding on the OpenVPN server machine.
