Properly Configuring a router.

I'm actually asking for Gravity since we play on a LAN at his house when ever we can. He's got a 5port router, a 4 port switch, two connections on his lan card and 3 IP adresses through COX cable. Basically we want to be able to run at least one extra computer behind the router so it won't need an IP, since we will end up with a total of four connections.


I'm not really the guy to talk to since I just have a computer there, but both times we've done it so far we have to screw with the cables to get the LAN thing going. I'd like to just be able to plug mine in and start some Starcraft etc.

Are the ips that you guys get from cox consecutive..? Like:
64.128.15.29
64.128.15.30
64.128.15.31

Or are they assigned via dhcp...?
You can pm me if they are not consecutive...

I do know they are DHCP because a fourth computer connected to the swich will not connect and you can't release or renew IP because it can't access the DHCP servers.


On monday I hooked mine up to the cable connection to download an update, and at the end of the night we couldn't get Joe's connected for this reason. I even released it from my machine successfully, but he had an IP listed from his machine, but no connection, and I didn't know how to force a renewal on it.

well on all nt kernal machines, you can release and renew as follows:

ipconfig /release

ipconfig /renew

Check the ips it gives you, they may all be on different subnets. If that is the case then traffic from one machine has to go out to the cable company, through their router and back in on the other subnet...

actually squirre1 what hes is trying to get at is how can he have internet access thru my computer. our setup is like this. we have a cable modem that is connected to a 4 port switch and my computer and two others are conected to that for the internet. all ips are dhcp configured. when we run a lan i have everyone plug into the 5 port switch that is connected to myh secondary lan connection. what we are trying to do is be able to have the people that are connected to the secondary lan connection be able to access the internet thru my main lan connection, and to be able to have both the router and the switch able to acces the game i host thru both of my lan conections.

So you have the following equiptment:

1 router
1 4-port switch
1 5-port switch

Correct...

What model is the router... I know that seems to be a stupid question, but just tell me...

or better yet how many lan/wan ports does it have...

It sounds like you will need people who come over to your lan do as Squirrel said about an IP release/renew using Command Prompt. When they come in they already had an internal IP assigned from their home network. They have to recieve a new internal IP assigned to their individual PC's by the DHCP/Router. Once they receive new IP's they should be able to go out into the Internet as they are recognized by the DHCP/Router.

well this is what I am thinking.... If his router has an additional switch port....

Internet------->Router------Gravity as 192.168 DMZ Client
-This is just fill-----\___>Switch with clients getting 192.168

This would allow everyone LAN side to see gravity and play on the net if necessary and would allow outside games to connect to gravity because he is in DMZ and is spoofed as the WAN side IP....

Feedback...

Can't find the link right now, but I know there was a link on Slashdot awhile back about a method that allows for providers to determine how many machines are hidden behind a NAT system - basically boiled down to the fact that each hardware manufacturer actually includes the number of IPs assigned by DHCP as part of the IP packet. Upside for us folks is that every manufacturer does it differently so it's not so easy to break down. Simplest way to get aound issue (Comcast was noted as being one of the first providers actually watching these things) was to daisy chain two routers in a row. Will add the link if I can find it - was actually a research paper written by some college professor or something.

That was quick, found the link I was looking for:

Oh man, too much reading! My brain hurts!

Here's a link to linksys where the breakdown is much easier and pleasant to the brain....Linksys Router

so here is how it is. the cable modem is C. the 4 port switch is A.
my computer is ME and teh 5 port router is B.

A is a D-link switch II dss-5+ and B is a 3com homeconnect

i can run a lan game of B while having my internet connection thru A. we know that we cannot have more than three computers on A or B (if A or B was the only router/switch between the computers and the modem) access the net at one time

what we are trying to accomplish is to have the people that are attached to B, be able to access the internet thru my computer.

or would it be easier to daisy chain the router and switch?

my computer has two independent NICs that are part of my mobo and con run both connections at the same time.

i not sure but i was thinking that if the router B was going thru my computer than it would show up as my net traffic not an independent ip thus allowing more than 3 computers

anyhoo im off to read to much on the affore mentioned article

Unless you've got some kind of special circumstances you need control of, I'd just say go

Modem -> Router -> Switch

Simplest way to do it.


Presumably, if they've got four ports each, you can have 7 extra computers plugged into the network (Three extra open on the router, one being used to go to the switch, then four on the switch).


Of course, you could always set your computer up as a DHCP, and go Modem -> Router with DHCP off -> Your comptuer with the lan bridge turned on-> Switch plugged into your second LAN port... etc... more work, but possible.

Modem ->Router ->Switch = LAN
