Hi everybody, I would really appreciate suggestions in helping me setup a network. I am a newbie when it comes to networking however, that does not go without saying that I did try abit until... I found that it was time I ask for help.
What I wanted to do originally, was have x amount of clients access the LAN only and have control to allow them to have access to the internet when time permits.
Being that I have read the mega 100wr manual and could not find a way to have the clients access the lan only I have chosen to follow this route instead.
Have a server and use it as a proxy. assign the clients IP addresses manually and not via DHCP.
I can successfully connect to the router when dhcp is turned off but after a while I have no connection and thus have to restore the router to the default settings and leave it as normal.
So, is there a way perhaps that I can allow clients to have LAN access on this router only, and also is there another way which I could perhaps set up my network with the above info?
I appoligise for the long text, and your help would really be appreciated.
 
I am pretty tired so i could screw this up....but i am a little lost.
and not really sure what you want to achieve here?

u wanted x clients to access the LAN normally but only internet during certain time periods?? is that correct?

have u got a proxy server setup already? If so what?
why do u want to use manual ip's?

What do you mean lan access on this router only??? Do you have multiple networks?

Hi,
When I refer to LAN access only I would prefer them to access local resources i.e. sharing a printer over the network, copying files from pc to pc but not accessing the Internet.
I had put the accessing Internet at certain times since I wanted them to access the net when I would change the settings where they can access the net rather than just the stuff on the LAN.
With regard to the proxy, I am considering that method of restricting the clients since I could not understand how I would have the clients access the LAN only rather than the Internet.
The program which I was going to use for dealing with the proxy is called CC proxy.
A friend who uses a netgear router says its possible where clients only access the LAN rather than the Internet.
I wanted to turn dhcp off as when clients connect to the router it does not assign them an IP address.
I hope that I have provided a sufficient amount of info as to what I am trying to do.
Bear with me please, as I am rather new at all this.
 
Sounds to me like you need to run a DHCP server and configure that to only give the client PCs their IP address and not the Gateway IP of the router.

Hi,
Thanks for your Input.
Originally, I would have prefered it if DHCP were turned off.
If I didn't give the gateway of the router, how then would it be possible for them to share resources etc as I am using the router to share them.

Regards,

Why not just turn on MAC address filtering on your router? everyone will access internal LAN, but wont be allowed through the WAN port unless their MAC address is on the list?

Hi,
I had not considered mac filtering as I understood it to block those trying to access the router regardless of whether it was wan or lan.
I do understand that one can allow certain devices on the list but would those people not automaticly get access to the wan as well as the lan?
if your suggestion is possible which I'm sure is, would you know of a way to do it on the mega 100wr router?
As I am really unsure as to what I should fill in at the following:
Src MAC
Src Port
Dest MAC
Dest Port
Protocol
However, the SRC mac is obvious if I must add.

Thanks much for your input thus far.
 
you either need to have the proxy server do some type of access control with regards to hours of internet access, otherwise everyone has LAN access and internet access.

so it's either a software options (proxy server with a timer options) or a hardware based one(router)
 
doesnt ur router come with some kind of firewall on it? surely you could configure rules on it to block internet access?

I think you may be right on the MAC filtering, I was hoping you could assign it to a port, but its most likely it is for all ports.
 
If you would like to have LAN access for all computers but no internet access, use DHCP in the router, but don't let it give out a default gateway address. All the computers can still connect with each other but they will be unable to go onto the internet.

To get them on the internet, you can then set up a proxy server, and put that IP address into Internet Explorer/Firefox etc... That way they can browse the net, but unless people know what they doing, most other internet applications that don't support proxies will fail to work.

Unfortunately the kind of set up you are thinking of isn't all that easy without setting up some sort of server. Can be done but it's primitive.
 
Hi,
Thanks for all the posts thus far.
I think then the best setup for me, would be the proxy route. as well as using DHCP.
But how not to give the gateway out is a mystry I've yet to solve with this Mega100wr router.
I personally think the help is rather vague with regard to examples as they sometimes give examples in certain sections of the help.
If anyone has a mega100wr router and has successfully used DHCP without giving out the gateway, I'd really be appreciated if you could give some info on how to do it. as when i turn off dhcp, I do not find anything with regard to IP address of the gateway.

Regards,
 
I did mean a DHCP server as from a dedicated Network server e.g. MS or Linux
 
I don't think you can configure the DHCP server in the Mega router to exclude the default Gateway. I've just looked at my Mega 105 now, and I can't find the option to exclude it. I think your best bet is to run a stand alone DHCP server.
 
Just so there's no confusion, the OP would need to turn off DHCP on the Mega router, otherwise it will conflict with Windows Servers' DHCP.

I would also suggest running WSUS on the server for the clients to have updated OS & software which will also save the internet connection in the long run.

Hi,
could you perhaps please give me a run-down of how one would go about doing this please? As I am totally new to all the networking and have never done it before.
Your help would really be appreciated.

I see by one of your earlier posts you are planning to use Windows DHCP server. Good idea, but what version of Server? 2003 or 2008? They both fairly easy to set up, though there are slight differences. Once I know what version I can help further.

Hi,
upon your recommendation to use a stand-alone DHCP server, I had googled it and results only showed that it can be setup in windows 2003 and 2008 like you had mentioned.
However, amongst all the results I spotted a program called AlaxInfoDhcpServer.
This program I think provides the functionality of the dhcp server which one can setup in the respective OS which was mentioned.
I will give this program a try, and provide progress as to how things are going.
Thanks much for your help thus far,

regards,
