I m not so much expert in networking but I have been working in this field for about
two years. I have been involved in network deployments as well as administration and I suggest
u the following points for your questions
basically the network ip addressing scheme is such a way that u use the ISP ip on WAN
interface of the router only. on Lan and pc,s u should use private IP addresses
now in the case of 200 computers u must use a server the server can be server 2003 or
2008. this is necessary to manage such a large number of systems at a single place.
when u use single IP on Wan interface and large number of private IP addresses then u have to\
enable nat overloaded on your router. some of the routers has by default enabled Nat. but
in some cases u have to configure it manually.
if u need any further help u can contact with me i will provide help to u to my best.
Hi all, I recently started trying to understand how networks are setup, primarily because of a school project I have to make in which I have to simulate the creation of a network from scratch in an enterprise, I don?t need something very elaborate, just basics. I?ve read some useful posts on this forum and I thought I might as well ask something that I have not understand quite well yet. I?m supposed to include at least 200 PCs in the network I?ll simulate, so I?m thinking I should just use a single real ip address from an ISP on a router, then connect this router to five different switches, all of which will have 40 PC?s connected to them, I guess this way the real IP address would be setup on the router and then I would be able to setup virtual addresses to every computer that is connected to a switch. Now my questions are:
1. Is it ok to use a single real IP address for such a high number of computers? The router would only really be connected only to five switches and I?m guessing it should be a very fast connection, like 100mbps or something.
2. Is it ok to setup the network just like that? Or do I need some kind of server or those layer 3 switches I?ve been hearing about?
3. In case I used more than a single real Ip address, how would I connect them? Would they each need a router? And in that case, how would the routers communicate with each other?
Any help would be really appreciated
