RBridge is a site-to-site Layer 2 VPN solution. It connects two distinct Ethernet LANs just as plugging a very long network cable over the distance, from one switch to the other.
As soon as two remote switches are connected with RBridge, all devices on one side can communicate with the devices on the other side as they would all be located in the same Ethernet LAN.
Operating with true random key material makes it the most secure Layer 2 site-to-site VPN solution available on the market.
RBridge easily traverses NAT devices like typical DSL routers on one or both sides.
RBridge comes with its own protocol level packet fragmentation and reassembly mechanism. This avoids any problems commonly occurring with standard UDP fragmentation (like flawed device implementations and firewalls blocking UDP fragments).
RBridge deployment is almost “plug and play”, just a few parameters need to be set to establish an encrypted Layer 2 site-to-site Ethernet link.
RBridge is free of charge for the Raspberry Pi.
