Objective: I made all local users (LAN) behind a PFsense firewall access the internet through a Linux CentOS with Strongswan to establish a VPN IPSEC site-to-site between both PFsense and Strongswan. The LAN users are behind the PFsense firewall, and the proxy is a Linux server running Strongswan as the VPN software.
