Hi, this might be of interest to you: https://code.google.com/p/badvpn/ Peer-to-peer VPN The VPN part of this project implements a Layer 2 (Ethernet) network between the peers (VPN nodes). The peers connect to a central server which acts as a chat server for them to establish direct connections between each other (data connections). These connections are used for transferring network data (Ethernet frames), and can be secured with a multitude of mechanisms. Notable features are: * UDP and TCP transport * Converges very quickly after a new peer joins * IGMP snooping to deliver multicasts efficiently (e.g. for IPTV) * Double SSL: if SSL is enabled, not only do peers connect to the server with SSL, but they use an additional layer of SSL when exchanging messages through the server * Features related to the NAT problem: 1. Can work with multiple layers of NAT (needs configuration) 2. Local peers inside a NAT can communicate directly 3. Relaying as a fallback (needs configuration) More info here: https://code.google.com/p/badvpn/wiki/badvpn P. S. It would be nice to see this with easy to use GUI and prepacked binaries for all "main" systems... Regards, M.

i love the concept of L2 VPNs; so pure in theory. (AppleTalk and IPX over WAN? no problem!) in practice they need a lot of careful implementation and configuration. the attack surface for tap vs. tun is very different; many services handling broadcast traffic assume a trusted local network environment. all of the security features listed on the wiki are related to transport / authentication rather than endpoint service considerations. this should be remedied. looks interesting! perhaps i can play around with it soon... best regards,

Very interesting project indeed!

It would also be nice to see this hosted somewhere outside Google... -- Pozdr rysiek
