  • had a brief introduction of freeRouter networking Swiss army knife
  • learn how to deploy 2 instances of freeRouter and interconnect them via 2 UNIX sockets on a VM guest running on VirtualBox 
  • this setup is ideal, for network simulation encompassing hundreds of nodes, self contained in the same VM without interaction with the external world. (protocol experimentation, convergence test etc.)

  • FreeRouter is using UNIX socket in order to forward packet.

All the feature set is IPv4 and IPv6 compliant. So there is no compromised !
