Projects / RBridge


RBridge is a secure remote Ethernet bridge solution for Linux. It connects two trusted Ethernet segments remotely over UDP using either IPv4 or IPv6 transport. RBridge uses SHA-2 (precisely SHA-256) for authentication, AES for encryption and timestamps for protection against replay attacks. Using a registry mechanism and UDP protocol, RBridge is able to connect directly to the peer from within NAT or firewall protected areas by using a special hole punching technique (thus requiring no configuration at the connecting routers). For this functionality, RBridge itself is able to act as a registry service for any associated pair of RBridges.
