Help designing network, Link 4 separate network Options

[banz]

Sorry about the bad grammar and bad drawing. But think I've just got a fever walking under the rain this morning, not feeling so well.

1. I'm trying to link these 4 separate network together A-B-C-D.
2. A B and D both have its own internet.
3. C uses internet connection sharing from B.
4. D is a private network not linked yet
5. They are all Windows xp pro machine including the main PC which links them.
6. PC is mainly connected to B as it's only got 1 wifi card enabled. Seems like if I enable both wifi internet on C dies. (I think its to do with the routing)
7. I'm going to link network D to PC as wired and not wireless.

I want to keep them all in different subnet (if that is the correct term). C will only be using B internet. I want the four network to be able to access each other (file share) also maybe plan lan games (but not high priorty). Currently only PC have the ability to access A B and C files. Since its acting as a router.

I have tried using windows to bridge the network, but it does not work. When I bridge A B and C the wireless connection to A and B on PC will disconnect leaving only C connected. Maybe again its got to do with windows routing?

So I'm a bit stuck and I don't know what to do. Is it to do with windows routing? Or should I install ubuntu or some other distribution? As I have heard linux is much better for networking. Only problem is I'm not that great at linux. I have a laptop with ubuntu on but setting it up as a dhcp pxe server took me like the whole day.

So can someone give me a hand on linking these 4 different network?

Thanks,
BaNZ

Sorry for the "stupid" question, but why dont you use VPNs?
Its much easier to connect the whole network via VPNs and a Hub/Switch/Router... whatever you want!

I have never tried setting up vpn, but anyway I have sort of managed to solved 3/4 of the network. They are all pretty much linked now and can access each other.

I have set each router to route the traffic correctly. However I'm unable to get C sorted as its behind an AP and its not a router. So any computers behind the AP cannot ping the other subnets. I think I'll need to play with the routing table more on either the server or the pcs behind the AP.

its not the "dns suffix" LOL

you have to do what is called subnetting

for example if you have a subnet mask of 255.255.255.0 now you could split that network into two seperate networks by using the subnet 255.255.255.128

giving you to sets of ip ranges

.2 - .127 and .129 - .254

First off sounds like your going to have some fun on this network, and I will try my best to help you.

First thing to do, is just make it so that there is no bridges or anything like that just simple connections.

Ok now I need to know all the IP address for every system, C has more than one network card. Also I need to know what the IP address' are on the wifi routers cause it looks like there is 3 wifi AP's involved. The more details the better.

You will also need to setup routes on each system. example: a to b would look like this:

route add 192.168.1.1 mask 255.255.255.0 192.168.5.1

which means: when A want to hit B it talks to C to find out which way to go and C knows where B is so C tells A where it is. Cause right now A is using its Defualt Gateway to find B and its default gateway is the internet... so its going to the internet to find B... which will not work.

Really this is Networking 101. Here is the problems that I see, your diagram does not have all the into on it, you have more than one IP addresses on C and I need to know them. Its ok to have A B and D as DHCP but C will need to be Static meaning unchanging. Each network card will have its own IP Address on the corasponding subnet.

Hope this helps if you need more help let me know.

If you really want an easier solution that goes over the internet use hamachi its slow and needs internet but it works. Its a free VPN software, that you can put 15 different clients on it.

Good Luck and have fun.

Thanks a lot! I have managed to get it to work. However it did took me quite awhile to setup the routing table as each router seems to have behave differently. I redraw the diagram this time and did it step by step. It is much easier trying to do everything at once.

I got hamachi installed on 80% of the machines. It is a nice software that I've been using for half a year. But it is more difficult to manage since the user would need to logon before hamachi starts (free edition).

My next plan is to use pfsense which will load balance wan! We should have a combine 10mbit connection soon if I can get it to work
Thanks a lot for your time!
