Need help Cascading Routers

[curtis1552]

I'm living at a friend's house and need to get my computers all connected, so I got a router from the classies, a WRT610N, because I want the 'future proof'iness of the wireless N. (I knoe I should still have gone with something that DD-WRT properly supports, but hey, it's 802.11n)

Anyway. He has a Dlink router connected to his cable modem and I want to attach my wrt610n to this to allow me connectivity for all my computers.

I tride the basic idiot-proof setup guide on the linksys site, and it doens't work.
There is a discrepancy - it says to go under Advanced Router settinga nd select router as the operation tyoe, but that section doesn't exist on my router.

I've tried this so far:
Changed Router IP to one that doesn't match any other routers/modems on the network.
Disable DHCP server on my router.
Tried playing with various options; RIP, NAT, and static IP addresses.

The best i've been able to get is for the router (not computers conected to it) to ping websites on the internet.
My router will not forward DHCP requests to computers connected to; it's still acting like a good 'ole router and not a proper switch.

Any help on re-configuring this would be appreciated. Once I get his up I can have a few more machines folding.

I am not familiar with Linksys's Router Web interface so I will just indicate generally what you need to do.


DHCP : Disable your router as a DHCP server and specify the primary router's IP address as the DHCP server.
DNS : Static DNS server, enter the router's IP address as the primary DNS server.
NAT : Disable NAT on your router.
Routing : Enable "Dynamic Routing (RIP)" I believe this setting will share routing info with you primary router and allow you to talk outside of your network.Like I said I am not familiar with your router so this is just roughly what you need to do.

When I have time tonight i'll give that a shot. The main difference is you mentioned i need to set up the DNS server.

You need a crossover cable I believe.

[curtis1552]

Why would I need a crossover cable? Routers/Switches/Hubs properly direct the incoming data from any type of patch cable. Also if I needed a patch cable the router wouldn't be able to transmit to the other router.

EDIT.
Finally got it.
1. Disabled DHCP server.
2. Enabled RIP
3. Disabled NAT
4. Left 'internet connection' on DHCP.
5. Plugged internet router into regular port, not WAN port.
6. (Here's the important one) Received IP from router with DHCP enabled (initially found on the router's Status page. Then set the router's IP to MATCH it. In this case 192.168.0.196. -now the status page has the IP as loopback and DNS set to the IP of the router hooked ot the modem.)

7. Got on OCF to post more.
8. Burned Ubuntu 9.04 CD's to set up folding comptuers.

Good to hear it.

I meant you would need one to plug into the wan port instead of one of the other ports.

Typicaly you just plug port 1 on your router into port 4 of his router and enable dchp on your router. It shoudl obtain an IP from his, and distribute IPs to computers that are connected. Thats how mine is working.

I was just thinking that if it is plugged into the wan port you get 1 more lan port. Either way, both methods work.:beer:

[curtis1552]

When you plug it into the WAN port it separates that LAN segment onto another network, not allowing access to computers connected to the other router.

[cyberfish]

The easiest way is probably to just connect the second router to a LAN port of the first router, and make sure they are on different subnets.

That way the first router would be like an ISP to the second router, and you don't need to change anything on the second router.

Performance may not be optimal, though (double NAT'ing).

[ppe1700]

you can disable rip. rip is "routing information protocol" and turning it on will start the router trying to talk to another route to exchange routes. there is a good chance that the other router is not even setup to use it, so you can safely turn that off.

good job on sorting it !

[Mike Wolf]

Connect port 1,2,3, or 4 on router 2 to port 1,2,3,or 4 on router 1, disable DHCP on router 2. Or you could just replace your friends router with your wireless router, and connect a switch.

[curtis1552]

1. I don't have a switch, and hubs are POS which i do have.
2. That didn't work, I had to set my router to the IP that the other router assigned via. DHCP it before it would recognise it as a router and let me send information through it.

Anyway.
