GVPE creates a virtual ethernet (broadcasts supported, any protocol that works with a normal ethernet should work with GVPE) by creating encrypted host-to-host tunnels between multiple endpoints.
Unlike other virtual private "network" solutions which merely create a single tunnel, GVPE creates a real network with multiple endpoints.
GNU Virtual Private Ethernet is designed to be very simple and robust (cipher selection done at compiletime etc.), and easy to setup (only a single config file shared unmodified between all hosts).
Vpn hosts can neither sniff nor fake packets, that is, you can use MAC-based filtering to ensure authenticity of packets even from member nodes.
GVPE can also be used to tunnel into some vpn network using a variety of protocols (raw IP, UDP, TCP, HTTPS-proxy-connect, ICMP and DNS). It is, however, primarily designed to sit on the gateway machines of company branches to connect them together.
What's New in This Release: [ read full changelog ]
· This release mainly updates the embedded event library and fixes some timer-related issues.
· Also, ICMP/TCP and HTTP-proxy protocol support is now enabled by default, as those methods are now deemed to be as stable as the existing UDP and raw IP protocols.
· Also, the DNS tunneling protocol has been tweaked further.
