QC Ubiquiti EdgeMAX - Site to Site IPsec VPN to Linux Server (strongSwan)

This video focuses on establishing a site-to-site connection betwee a Linux server running strongSwan and an EdgeRouter. The EdgeMAX platform basically runs strongSwan in the background, so we can 'steal' the configuration and apply it directly on the Linux server. In the video I also talk about general encryption settings, IPsec parameters, Dead Peer Detection (DPD) and other recommended settings. Please see the link below for the Servercentral blog, which in my opinion is a very informative read.
