How to network these 2 cable modems?

[Ace69]

Here is the deal. Me and my 2 roomates have 2 cable modems running from two separate jacks. The roomates are sharing 1 cable modem with a 5 port switch. I have the other cable modem, --> running to a Linux router --> to a hub and --> the hub going to my PC. My question, how could I network these together? Can I simply run a cable from their switch to my hub. It makes me wonder because they are getting incoming traffic on their modem and I am getting incoming traffic on mine as well. I don't know how those would combine. I may be missing some information. Ask and I will tell..

Thanks for the help..

You would need to connect on the router level to keep integrity. To connect hub to switch one has to uplink off of the other, and they both would have to be on the same subnet. You need router level communication to redirect the packets. Both routers need to support 2 WAN and 1 LAN connections.
You could try adding a second network card to each computer and connect them all to a hub and use a shared subnet. Problem with this is you can experience wierd problems depending on the OS and the placement of the cards ( like IE looking for the first card for DNS always, even though the MS networking functions fine).

From what i understand, the way i would do so is like :

(( Internet )) ---> (( Router )) ---> (( Linux Firewall )) ---> (( hub/switch )) ---> (( all the stations ))

The router MUST have 2 WAN ports and at least 1 ethernet port to output to the linux firewall.
The firewall/gateway have 2 NIC, one on the router, the other connected to the switch with all the users linked to it.
If possible, everybody should go with 10/100 NIC in full-duplex to take benefit of the bandwith available
