Re: Router setup problem is it possible to use only a switch instead of the second router to host a lan party?
also, if this is possible, is there a security risk from the other computers being able to access the files on mine? i'm running xp. |

| If you are just wanting to connect a bunch of computers together on a LAN, with no link to the outside world, then a switch will work. There is a problem, however. You would either need to manually assign an IP address on each of the computers, or you would need to run a DHCP server on one of them. The use of a router (with no WAN connection for that router) solves the DHCP problem, provided that its DHCP range does not conflict with other IPs in use (on your other network interface).
Whether there is a security risk depends on what you are trying to do. If you are running a firewall, you can block access to your files from other computers. Or, if you want to make them available, you can share them read-only.

| what did you mean by this?
"There is a problem, however. You would either need to manually assign an IP address on each of the computers, or you would need to run a DHCP server on one of them."
if i do not require any of the people in the lan to have internet access except myself, do i still need to assign an ip address or run a dhcp server on them? |

| They still need an IP address to communicate on the LAN. It can be a private IP address. And the computers are probably setup to expect to acquire an IP address using DHCP.
You don't need to run a DHCP server on every computer. You just need something on the LAN that is running a DHCP server. Your second router will do that.

I'd do as nwrickert  recommended.
Configure Ethernet card 1 as a DHCP client.
Connect your Ethernet card 1 to Router1.
Set up router1 for gaming, no WAN(internet) connection, with LAN address of 192.168.10.1 and as a DHCP server for the 192.168.10.0 network.
Router1 will now serve addresses of 192.168.10.xxx to PCs that connect to it.
Then,
Configure Ethernet card 2 as a DHCP client.
Connect your Ethernet card 2 to Router2.
Set up router2 for WAN(internet) connection, with LAN address of 192.168.20.1 and as a DHCP server for the 192.168.20.0 network.
Router2 will now serve addresses of 192.168.20.xxx to PCs that connect to it. These PCs will be able to access the internet.
Unless you want to share connctions between the two cards, do *not* bridge connections between the cards on your PC.
Note that you can configure Windows Firewall for each LAN card on your PC, so you can customize access to your PC as needed for each card.
