Additionally I have a notebook, that is linked with a laplink cable (PLIP) to one of the PCs. The other PC has a modem that hosts a SLIP route to the internet. PC PC notebook INTERNET-slip-NEPUMUK-ether-PLOCUS-plip-LIBERT NEPUMUK has only a host address granted by the provider, so I can't use it as a packet forwarding router to the world. Therefore I must use addresses on my little network that do not conflict with the addresses in the world. I guessed that there are no addresses in the world that start with 127. So I have now two Class C subnets: 127.1.0 on the ethernet, and 127.1.1 on the PLIP line ETHERNET PLIP SLIP LOOPBACK NEPUMUK 127.1.0.1 160.45.216.109 127.0.0.1 PLOCUS 127.1.0.2 127.0.0.1 (plocus-lap) 127.1.1.1 127.0.0.1 LIBERT 127.1.1.2 127.0.0.1 PLOCUS has packet forwarding capability switched on while nepumuk has this switched off in order not to send out packets with local host addresses to the world. The local network works somehow but not really satisfying: (1) LIBERT is not able to ping himself by his PLIP address. (2) each site can only connect its direct neighbours i.e. PLOCUS does not route any packet from ETHERNET to PLIP or vice versa. I suspect that I made some mistakes using the 127 and the 0 bytes as network addresses, since both are special. But which addresses are save to be used in an unofficial network? Is ther a manual or tutorial teaching me how to set up small local networks? How do I have to deal with netmasks? any help is appreciated! regards -- Gunther Schadow-----------Windsteiner Weg 54a, Berlin 14165, FR.
