| Router setup problem my computer has 2 ethernet jacks. one is from the on board lan, while the other is from the ethernet card that i put in. my intention in doing this was to have 2 networks: one connected to the internet, and one not connected to the internet (the second one is only for lan gaming). i have 2 identical wired routers with which to do this.
i have never had problems connecting to the internet from one of the ethernet ports. however, when i plug in the second identical router into the other ethernet port, my internet doesn't work anymore. i have tried a lot of things, including telling my second router to not act as a dhcp server. it just doesn't work!
is it possible to set up my computer such that i have internet access and at the same time i am connected to my gaming lan? i suspect there is a conflict of some kind between the routers, but i don't know how to resolve this conflict. the routers are rpn 614s. |

| The two routers need to use different LAN ip ranges. Since they are identical routers, this won't happen unless you configure one of them to use a different LAN ip range.
Example: Some routers use a LAN IP of 192.168.1.1, and assign IP addresses (the DHCP range) from 192.168.1.2 through 192.168.1.100. This is usually configurable. So you configure that router to instead use 192.168.2.1 as its LAN IP, and then check that it also changes the DHCP range to match.

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.

alrite, after i configured my routers with different ip ranges as described above, i got the following error message:
"the object you requested on the server is being used by someone else ([an ip here with the first 2 groups of digits the same as the ip range set up on router2], ""). please try again later."
what does this mean? this message only appears when router1 (no WAN) and router2 are both connected. if router2 is the only one connected, my internet works normally, since router2 is the router i use all the time. the instant i plug in router1, router1 works well for the lan gaming, but the internet doesn't work. what i mean by "doesn't work" is that when i open any browser, i cannot navigate to any web page, and the error message above is displayed. please help! how can i both have internet access and keep router1 up for lan gaming? |
