SoftElegance has successfully created a VPN (Virtual Private Network) between two networks, separated by the internet, using FreeBSD gateways and over IPsec protocol.
IPsec (Internet Protocol Security) is a protocol suite for securing Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session. IPsec also includes protocols for establishing mutual authentication between agents at the beginning of the session and negotiation of cryptographic keys to be used during the session.
The goal is to set up IPsec using FreeBDS gateways.
