Connecting Two Networks via Hubs?

I am considering the following, but not sure what is the best solution.

Setup currently:
Two Networks. Network "A" is connected via an Ethernet Hub (3Com) which is then connected to a VPN (IBM) which provides Internet Access. Meaning Internet modem plugs into the VPN.

Network "B" is also connected via an Ethernet Hub (3Com) which is not connected to any VPN or Internet Modem.

Network "A" and "B" are about 40 feet apart. I was thinking it would be possible to connect the two together....what would be the best way to do this? Connect the two Ethernet Hubs via one port on each? Seems strange?

 
It's quite normal actually. What you need is a crossover cable (unless your hubs have a crossover port which is usually represented by an X).
 
Just as long as network A and network B are in the same subnet and you need to use the uplink port on the hubs to connect them together. If the 2 networks are not on the same subnet they will not be able to talk with each other.

not without a router or a box doing ip forwarding 🙂
 
Thanks Folks.

Actually I am concerned little about the Networks talking to one another at this time....just trying to get internet connectivity going.

Thanks

 
Fuzz why would you need a router or ip forwarding if they are on the same subnet, it's just going to a large broadcast domain. You need a router if they are not on the same subnet. As far as the internet is concerned they will need to be on the same subnet. otherwise yoy would need a router to route between the 2 subnets (if there not the same

It sounds like he will need a router for nat and internet connectivity anway, at least for network B.
 
From Kineses orginial post Two Networks. Network "A" is connected via an Ethernet Hub (3Com) which is then connected to a VPN (IBM) which provides Internet Access. Meaning Internet modem plugs into the VPN


so it looks like he already has a device that is natting for internet access

You sure about that?
 
Hey folks.

yes, the ADSL modem connects to the VPN, which then plugs into (port 1 I believe) on the Ethernethub (8 ports) of Network "A".

Network "B" is not connected to any internet accessible place, so that was why I was wondering if using a Cross over cable (or something else) to connect the TWO hubs would be a possible solution...

Or did I just confuse you all. Sorry, I am trying to be as simple and direct on this as possible.

Thanks again for any advice...
