I need to extend my school's network beyond the 254 IP numbers I'm using - based on 172.19.50.x
This network includes a router which links through an ISDN line to an LEA proxy server.
Is the best way to achieve this to split the network into 2 segment and use a Linux machine and Masquerading to link them together.
Will the routing at the LEA not allow you to simply have an extra 254 addresses? Change your allocation from 172.19.50/24 to 172.19.50/23, which will give you 172.19.50.0 -> 172.19.51.255 ( worked out, in my head, with a cold, so I may be right about the theory but wrong about the ranges ).
ie.- leave the bulk of the machines on 172.19.50.x use 192.168.0.x for the others use two NICs in the Linux machine, 1 for each subnet Install masquerading
Will this allow the machines on 192.168.0.x to access *all* the services on the main network?
Depends on the services used, but if you're going to use masquerading only but no firewalling there probably won't be any problems. I would have thought there's a more elegant solution though - you may be reconfiguring a lot of TCP/IP stacks over the summer holiday....... -- Nick Drage, helping fill up the internet since 1993.
