I have a network of 8 computers all running windows XP (most Pro and some Home. I have both DSL and Cable now connected to a Hawking Dual Wan Router and the system is working fine. However, I would like to be able to setup the network so that One computer on the network uses the cable modem exclusively(fastest connection for online gaming only, security not an issue) and all the rest of the computers share the DSL connection. I have plenty of extra routers and switches to work with. Can I setup a standard network using DSL modem to Router to Switch and let the router hand DHCP and then connect the cable modem directly to the switch and setup one computer with static IP and manual settings to access the cable modem? Or is there a way to use 2 routers?

Just change the gateway address to refleck to which ever connection you want to use.

I am sorry the gateway address on the client computers. ( if you did a ipconfig @ the dos prompt you would see what I am talking about)

Since it is a dual wan router there is only one gateway and that is the ip address of the ethernet port of this dual router. You would have to go into the router and configure this workstations ip address to only go to the wan ip address you want it to. This would be the only way you could do this with your present setup. More equipment wouldn't solve this issue.

I don't think my router will let me do that, I will check it out. How about this: Could I use two routers, have one set for DHCP connected to the DSL modem. The other router DHCP turned off and connected to the Cable modem. Both routers connected to my 24 port Switch. Set the one computer for Static IP and Gateway of the router connected to the Cable modem. I would have to make sure the IP address of the routers are different. Does this sound feasable?

With a dual port router I would expect that you can configure a preferred route for a particular ip address. Just as I would expect that you can configure who goes to what wan port or what to do if one wan fails. Your plan would work. Router1 would have a .1 address and the other a .2 as an example. You would set everyone to get dhcp except this one workstation. This one station would have the .2 for gateway and a static address but in the range of the subnet you are using for dhcp. So lets say you have 192.168.0.10-20 for dhcp. You would give this station 192.168.0.21

linux kernel 2.6 supports advanced routing. i.e. routing by source ip :) sweet. if you plan on ditching your dual wan router i'd do that.
