Can you push a specific gateway across a Linksys Wireless Router?
My company is using a Direcway Satellite uplink to provide internet connection to some media people. We want to be able to provide the media people with internet access as easily as possible.
The internet connection is setup in a remote area via a Direcway satellite which is controlled by a laptop running Windows 2000 Pro. The laptop acts as the gateway for anyone on the wireless network. There is a Linksys router tied to the laptop, and the router is setup to allow a limited number of connections.
The IP scheme in place is 192.168.1.x
The router is 192.168.1.1
The laptop acting as the gateway is 192.168.1.101
The router provides DHCP to wireless clients in the following range 192.168.1.151 - 192.168.1.200
We have provided a number of laptops access to the internet by giving them static IPs between 192.168.1.50 and 192.168.1.100, and by forcing them to use 192.168.1.101 as their gateway.
Our problem arises from the fact that the Linksys .B/.G wireless router will not allocate a gateway other than its own IP. We've setup the laptop to allocate DHCP, and turned off the DHCP on the Linksys router, but the clients don't find the laptop and don't receive DHCP IP addresses from the laptop.
My questions...
1. Can anyone recommend a reliable, cheap, wireless router which allows you to specify a gateway other than itself?
2. Does anyone know a way to configure the Linksys router to pass internet requests to the laptop (192.168.1.101)?
3. If you can't answer 1 or 2, can you recommend a way to troubleshoot why clients connecting to the wireless access point don't receive the DHCP info from the laptop- when the DHCP server is turned on?
All help or feedback is appreciated. Thank you.

I have setup the laptop to push DHCP to the wireless network, but the clients were unable to see the DHCP server, so I turned it off and turned the DHCP functionality on the router back on.
Any ideas on why the clients might not have been able to receive DHCP addresses?

Why are you double NATing? What is the purpose of routing your traffic twice?
You can set your laptop as a DMZ on the router and that will forward all unspecified traffic to the laptop.
And im not sure how its using itsself as a gateway. The linksys heap should be using the modem or whatever satalite users as the gateway. and the laptop should be using the linksys as its gateway and so on down the line.

Google DHCP relay agent.
Having a flashback from school. I dont think all routers relay DHCP. That would be a security issue.

Ecszone,
Thanks for the quick response.
I'm not using 2 DHCP servers or double NAT'ing. I made sure that only one of the 2 DHCP servers was serving at a time. I only had the laptop serving DHCP during a short test.
I'm not sure that the Linksys is routing the DHCP as the laptop.
Are you sure the Linksys would push I-net requests through the laptop if it was listed as a DMZ? That's something to try, at least.

oops... routing the DHCP "for" the laptop.

Additionally, I'll explain some more specifics about my situation.
The peculiarities of the Direcway satellite internet connection limit my ability to use ICS on the laptop. As soon as ICS is enabled, the Direcway software breaks satellite connection. So, I can't just enable ICS on the ethernet connection on the laptop, and use its ethernet port as the Internet connection on the Linksys router.
The Direcway is a very touchy system, and has forced me to use the laptop as the gateway.

Lets make sure i understand..
(satalite equip)---(linksys router)---(laptop running ICS)-------client1
|------client2
|------client2
Is this how they are physically wired?
And you are useing ICS correct? ugh hate ics.

No, it's setup like this...
(Satellite Equipment)---(Laptop Unable to Run ICS)---(Linksys Router) ..B/..G..Wireless..Connect

ASKER
I can't run ICS, because ICS on the laptop kills the laptops satellite connection.
Does pro have RRAS? So your running it as a router using NAT?
reanalizing now with new info....

Wait... are u using the router as a router at all (using WAN port)???
or is it just setup as a WAP? Seems like your more looking to have it setup simply as a wireless access point?

ASKER
Right, I want it setup as a WAP, but my issue is pushing internet requests through to the laptop. If I could set it up as a WAP and drive all non-local traffic through the laptop, that would be ideal.
Anything you can think up as a solution would be terrific.
RRAS is not in use. NAT is in play because the Linksys DHCP pushes IPs down to anyone connection to the WAP. The router really doesn't route traffic because it has no direct connection to the internet; I'd like it to route through the laptop.

There is no security on the WAP... I'll give that a try. That might work.
oh wait.
you will need to increment the router LAN side IP subnet.
ie clients and lan side will be 192.168.2.100 etc.
otherwise it will not pass the traffic forward.
so wan side is 192.168.1.0 lan side 192.168.2.0
understand?

So change the IP scope for the router from 192.168.1.x to 192.168.2.x? And make the IP on the laptop 192.168.1.1, and make it pass out DHCP along the 192.168.1.x scope?
ASKER
For that matter, I can leave the LAN side alone, and change the laptop to 192.168.0.x...
just change either one of them.
no the router will pass out using DHCP whatever its lan side is.
then the WAN port of the router will be tied to the laptop. So the WAN ips scheem will match the laptop, and the laptop will be the WANS default gateway.
(satatlite) ---- (pub IP***laptop*** 192.168.0.101) -------(192.168.0.1 *** LINKSYS *** 192.168.1.1) --- wireless clients
anytime a computer tries to go to an ip that is not the same subnet is itself, it defaults to the default gateway.
your linksys. The linksys will route it to its ext interface. If its not on that subnet, it send it to its default gateway. the laptop. and so on down the line.

esczone,
Thanks you've been incredibly helpful. I'll be in a position to test this at 8am EST tomorrow. I'll post feedback then.

Seems like I missed quite the show today....
Just want to add, that I have set up double-NAT without any problem.
I would have leaned more towards the relay agent, but hopefully this setup will work for you...good luck!

ecszone,
Good job! In retrospect, this seems like it should have been a real easy answer from the start. This worked for me without issue, although I will give this piece of advice to anyone paying attention.
WhenEver you have the option to choose a hardline (cable, DSL, T) over a satellite connection- choose the hardline. Our satellite connection split over wireless for multiple users, sucked. It straight-up sucked. This was my first experience using a satellite system, and I will NEVER use one again- until the technology makes VAST improvements.

Glad it worked for you. yea i hear satalite is not so good. To make it worse dsl/cable keep getting faster and faster! :)
