Hi, I'm doing a networking course and i have 3 virtual servers and 3 virtual client PCS. My servers are set up as routers for three different locations, i can ping between each router and client machine but i cant access the internet from 2 of the routers and 2 of the clients. i can access the internet from one of the routers and its corresponding client though. The router and client that can access the internet are meant to be the main outlet for internet access to the other 2 routers and clients. The internet connection is a NAT configuration.. I have setup DNS on the router with a NAT configuration and static routes etc... Does anybody have any ideas as to why the internet cannot be accessed by my other 2 clients and routers?

That's a hell of a way to teach networking, 3 servers as routers and one of them is the gateway for the other 2. Let's try it anyway. Show the IP configuration for the entire mess. Are any of them dual homed? For example: Modem: External IP Server1 IP address, Subnet Mask, Default gateway Client1 same info Server2 same info Client2 Continue with the rest of the network and explain what's running NAT.

Im not quite sure if Ive set this out right but here goes...

Currently i can use the internet from this machine and its client but i can't access the internet from the other two routers and their client machines. Not sure if any sense can be made of this, thank you for your interest anyway.

It makes some sense although I would never try to do it that way. I'm not sure exactly what you are calling a server and a router. Is each server a router too? How is one subnet physically connected to the other? In any case, you have 3 different subnets, 2 of which are not pointing to the 'server' that is connected to the net. Connection 2 with the IP Address 192.168.3.14 shows no default gateway at all, so it can't go anywhere. Were you told to use 3 different subnets? If so, routing tables have to be set to pass from one to the other, although I don't know how you could do that unless some of the computers were dual homed (2 NICs). Even if you wanted to have 3 different internal subnets, the best way to do it is to have a high end router as the gateway to the net and all servers and clients on all three subnets connected to it.
