Configure an IPSec VPN Gateway server on Linux and strongSwan

strongSwan is an open-source IPSec VPN suite that supports VPNs compatible with any other IPSec-capable device, including network appliances from most vendors, as well as VPN Gateways of major cloud providers. It can be configured to handle both Site-to-Site and Remote Access VPNs at the same time. I can assist with deployment, configuration and further support of this solution: define new connections, implement NAT to meet standards requirements and fully integrate into existing network infrastructure.
