Here is my scenario:

My friend is sharing an office with another company. One company has 6 PC's and the other has 2. Right now they are sharing the same internet access through a 4 port router. What they want to do is to separate the two companies so that they do not share the same subnet. I guess what they really want to do is to have different domains (or actually be able to use their own mail accounts (example mail@office.com). Is there a way to do this with a router or would they just need to get separate accounts through the ISP??

if they have at least to ip addresses from the isp they can make 2 diferent domains, and the clue be defining diferent gateways for each domain, i mean subnet, it be defining the proper network addresses for each sub network, using the same router, but if you can spend some bucks on a new router, they can have separate connections, and make the same thing on both of them changing the net address of each company. for security i mean.


see you

okay, now the question is how would this work out with a wireless infrastructure?? Would I have to use a VPN to separate the networks?

i dont think you need to use a vpn in order to separete two networks, lets see, you could do it with a wireless bridge.

i hope it works out for you

Ok...let's see:

-2 Companies, say, ABC company and XYZ.
-1 location: the office
-1 DialUp or Access to Internet

What could you do (or at least, what i could you in your case)

ONE physical Subnet with 2 Domains

-You can have 2 different domains in the same physical subnet. Should not exist relation between them. So, you could create/separate 2 differents NT or W2K Domains: one for ABC company....another one for XYZ company. Just SetUp 2 differents DC for each one.

-SetUp one DHCP Server in your Network.

-SetUp NAT in a Multihomed W2K machine (the machine with Internet access). Then, configure each DNS/DC Server (for each Domain) for reach internet access using the NAT Server. All client's gateway must be the NAT Server.



Should work...

Howdy Jocampo, what about the wireless stuff, what he needs is the hardware point of view, what i see would be a big problem is the phone bill, whos using what, ill switch to a permanet conection.

nice to see you around.

Hi Luisjo.

¿what wireless stuff are you talking about? I think there is only one location and office. And in that office, there are 2 companies working, sharing one internet connnection. Maybe i'm wrong, but that's what i'm seeing in his question.
