  │ If you intend to run your Linux box mostly as a router, i.e. as a                                                    │  
  │ computer that forwards and redistributes network packets, say Y; you                                                 │  
  │ will then be presented with several options that allow more precise                                                  │  
  │ control about the routing process.                                                                                   │

  │ The answer to this question won't directly affect the kernel:                                                        │  
  │ answering N will just cause the configurator to skip all the                                                         │  
  │ questions about advanced routing.                                                                                    │

  │ Note that your box can only act as a router if you enable IP                                                         │  
  │ forwarding in your kernel; you can do that by saying Y to "/proc                                                     │  
  │ file system support" and "Sysctl support" below and executing the                                                    │
