If you have the possibility to use a dedicated (virtual) server to setup a IPsec&#x2F;IKEv2 VPN server, have a look at pfSense[1]. It is easy to manage through the webinterface, especially when using IPsec with certificate authentication for road warriors. The current pfSense stable release uses strongSwan 5.3.2 for IPsec VPN&#x27;s.<p>Documentation for installing and setting up strongSwan from source is available on their own wiki[2]. There are also packages available for some Linux distributions.<p>This site&#x2F;blog[3] explains very well how to install and setup strongSwan with certificate authentication. But most of the examples are probably also on the strongSwan wiki.<p>[1] <a href="https:&#x2F;&#x2F;www.pfsense.org&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.pfsense.org&#x2F;</a><p>[2] <a href="https:&#x2F;&#x2F;wiki.strongswan.org&#x2F;projects&#x2F;strongswan&#x2F;wiki" rel="nofollow">https:&#x2F;&#x2F;wiki.strongswan.org&#x2F;projects&#x2F;strongswan&#x2F;wiki</a><p>[3] <a href="https:&#x2F;&#x2F;www.zeitgeist.se&#x2F;2013&#x2F;11&#x2F;22&#x2F;strongswan-howto-create-your-own-vpn&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.zeitgeist.se&#x2F;2013&#x2F;11&#x2F;22&#x2F;strongswan-howto-create-...</a>
