Editing Virtual private network (section)

=== Support in network devices ===
Network appliances, such as firewalls, often include VPN gateway functionality for either remote access or site-to-site configurations. Their administration interfaces often facilitate setting up virtual private networks with a selection of supported protocols. In some cases, like in the open source operating systems devoted to firewalls and network devices (like [[OpenWrt]], [[IPFire]], [[PfSense]] or [[OPNsense]]) it is possible to add support for additional VPN protocols by installing missing software components or third-party apps.<!--[[User:Kvng/RTH]]-->

Commercial appliances with VPN features based on proprietary hardware/software platforms, usually support a consistent VPN protocol across their products but do not open up for customizations outside the use cases they intended to implement. This is often the case for appliances that rely on hardware acceleration of VPNs to provide higher throughput or support a larger amount of simultaneously connected users.
