What is OpenVPN in VyOS CLI?
OpenVPN has been widely used on UNIX platform for a long time and is a popular option for remote access VPN, though it’s also capable of site-to-site connections. In the VyOS CLI, a key point often overlooked is that rather than being configured using the set vpn stanza, OpenVPN is configured as a network interface using set interfaces openvpn.
Can I host websites on a virtual server built with VyOS network OS?
Make sure that you understand that a Virtual Server built with the VyOS Network OS (VPN Appliance) template will only function as a VPN or router network appliance. It will do nothing else. You cannot host websites on this VS, or use it as a mail server, or for any purpose other than as a VPN or router.
What is the new password for the VyOS user?
PASSWORD is the new password for the vyos user. Since the vyos user has full access to configure the VPN, make certain to pick a very secure password. If your password is easily guessed, someone could compromise your VPN and access the systems and data that you are trying to secure. Consider using a secure password generator to create the password.
Why doesn't VyOS support IPsec?
Traditionally hardware routers implement IPsec exclusively due to relative ease of implementing it in hardware and insufficient CPU power for doing encryption in software. Since VyOS is a software router, this is less of a concern.

Public Key Infrastructure (PKI)
Phabricator Task T3642 describes a new CLI subsystem that serves as a "certstore" to all services requiring any kind of encryption key (s). In short, public and private certificates are now stored in PKCS#8 format in the regular VyOS CLI. Keys can now be added, edited, and deleted using the regular set/edit/delete CLI commands.
Firewall
Additional configuration may be needed if you have a firewall policy on the external interface.
Allow clients to reach external hosts
If you want the VPN to be used for external access (that is, allow clients connected to reach external hosts from the VPN server), SNAT will need to be properly configured:
Additional Configuration Options
A full list of configuration options for L2TP can be seen by hitting the tab key after typing set vpn l2tp remote-access:
What is Vyos CLI?
VyOS CLI requires TLS Authentication for client/server implementation. We need to create CA, create server and client keys and sign server and client certificates. For this purpose, we will use easy-rsa. It is a CLI utility to build and manage a PKI CA.
Does OpenVPN use X.509?
The use of server-client VPNs in OpenVPN requires X.509 certificates to be setup. For this purpose we are going to create a public key infrastructure (PKI), with the own certification authority running on the VyOS OpenVPN server. It will be used for issuing the trusted certificate for the server and clients.
What is Easy RSA?
OpenVPN ships with a set of scripts called Easy-RSA that can generate the appropriate files needed for an OpenVPN setup using X.509 certificates. Easy-RSA comes installed by default on VyOS routers.
What are the advantages of OpenVPN?
Advantages of OpenVPN are: 1 It uses a single TCP or UDP connection and does not rely on packet source addresses, so it will work even through a double NAT: perfect for public hotspots and such 2 It’s easy to setup and offers very flexible split tunneling 3 There’s a variety of client GUI frontends for any platform
What is Enterprise Installation?
Enterprise installations usually ship a kind of directory service which is used to have a single password store for all employees. VyOS and OpenVPN support using LDAP/AD as single user backend.
What is the port for OpenVPN?
The official port for OpenVPN is 1194, which we reserve for client VPN; we will use 1195 for site-to-site VPN. The persistent-tunnel directive will allow us to configure tunnel-related attributes, such as firewall policy as we would on any normal network interface.
Is OpenVPN a VPN?
While many are aware of OpenVPN as a Client VPN solution, it is often overlooked as a site-to-site VPN solution due to lack of support for this mode in many router platforms.
Is client GUI faster than IPsec?
There’s a variety of client GUI frontends for any platform. Disadvantages are: It’s slower than IPsec due to higher protocol overhead and the fact it runs in user mode while IPsec, on Linux, is in kernel mode. None of the operating systems have client software installed by default.
IPsec Site-to-Site VPN
In addition to being used with other protocols (such as L2TP) in a server-client VPN setup, another common use for IPsec is the creation of site-to-site VPNs.
Additional Configuration
If you have source NAT rules on the outbound interface, exceptions need to be added on each router:
What is IPsec router?
An IPsec compatible router or network appliance at your physical location. A static public IP address that is attached to the IPsec compatible router or network appliance. The ability to access and make configuration changes to the IPsec compatible router or network appliance.
Can a VPN password be guessed?
Since the vyos user has full access to configure the VPN, make certain to pick a very secure password. If your password is easily guessed , someone could compromise your VPN and access the systems and data that you are trying to secure. Consider using a secure password generator to create the password.
Does Vyos have SSH?
VPN configuration: Virtual Server Console. By default, the VyOS Network OS does not have SSH access enabled. Because of that, you will need to connect to the Virtual Server using the VS Console first, so that SSH access can be configured.
