Solved Inter connection among routers

Specs: Windows 8.1
Hi,
In order to use the MAC reservations available in the routers I have divided the users into 4 routers, allowing them to connect to the router in their separate departments. There are 32 MAC reservations available in each router. The first router is connected to the Internet.

There is a server computer that connects with the 2nd router.

The 2nd router is connected via wire to the 1st one and the 3rd and 4th router are connected to the 2nd. They are are also on wire.

I want to access the server computer from all the routers. Is that possible?

Thanks

Yes it is.

The simplest way would be to use one subnet for your entire LAN. Assuming you have less than 250 total clients we'll go with a /24 network

Example:

192.168.1.0/24

Router 1:
LAN IP: 192.168.1.1
SM: 255.255.255.0
DHCP enabled = Yes
DHCP Scope = 192.168.1.50 to 192.168.1.200

Router 2:
LAN IP: 192.168.1.2
SM: 255.255.255.0
Default Gateway: 192.168.1.1
Connected to Router 1 LAN port to LAN port

Router 3:
LAN IP: 192.168.1.3
SM: 255.255.255.0
Default Gateway: 192.168.1.1
Connected to Router 2 LAN port to LAN port

Router 4:
LAN IP: 192.168.1.4
SM: 255.255.255.0
Default Gateway: 192.168.1.1
Connected to Router 2 LAN port to LAN port

Since the server is going to need a static IP, pull one from the 50 excluded IP's.

Server:
IP: 192.168.1.20
SM: 255.255.255.0
DG: 192.168.1.1

Now every client, regardless of which router it's connected to, can access the server.

If you have a network printer (or more than one) you still have multiple IP's to use in the excluded pool for them. Or any other resource that may need a static IP like a NAS or scanner....etc.

It matters not how straight the gate,

I am the captain of my soul.

Dear Curt,
Thanks for your suggestion. I have tried it out already. By doing as you said, all routers (2,3 & 4) will work as switches making the 1st router the main network. By doing so only the 1st router's mac reservations will be available for use and there are only 32 addresses in each router. I think it is called router cascading style.

I want to use the mac reservations from all the routers that will allow 32 addresses from each of them. When the mac reservation is made, no one else can log on to the network even when the password is leaked.

I hope now you understand what I want. There should be a way to do this.

Well I have to admit, I've never tried using MAC reservations. I've also never tried something so complex on SOHO level equipment.

But it seems to me that you could split things up if you like.

Since you only need 32 addresses per router how about something like this:

Router 1:
LAN IP: 192.168.1.1
SM: 255.255.255.0
DHCP enabled = Yes
DHCP Scope = 192.168.1.50 to 192.168.1.90

Router 2:
LAN IP: 192.168.1.2
SM: 255.255.255.0
Default Gateway: 192.168.1.1
DHCP enabled = Yes
DHCP Scope = 192.168.1.91 to 192.168.1.130
Connected to Router 1 LAN port to LAN port

Router 3:
LAN IP: 192.168.1.3
SM: 255.255.255.0
Default Gateway: 192.168.1.1
DHCP enabled = Yes
DHCP Scope = 192.168.1.131 to 192.168.1.170
Connected to Router 2 LAN port to LAN port

Router 4:
LAN IP: 192.168.1.4
SM: 255.255.255.0
Default Gateway: 192.168.1.1
DHCP enabled = Yes
DHCP Scope = 192.168.1.171 to 192.168.1.210
Connected to Router 2 LAN port to LAN port

By splitting the DHCP scope evenly among the 4 routers this should allow you to use MAC reservations on each router and supply enough IP's per router. Just be very careful to not overlap your DHCP scopes. Each must be unique. In the above example I give 39 IP's per router which should cover your need for 32 usable IP address'

Dear Curt,

It seems it will work. I will try your new idea of splitting the DHCP.

Thank you sir.

Dear Curt,

Sorry for my late reply,

I just implemented the routers with MAC addresses as you suggested and it is working. It seems like it is the best to do so.

Since the implementation, I am having a new problem with the wireless network on all laptops. After applying their MACs on the routers, it can connect to any of the four routers with the same IP but I don't know why the wireless connection doesn't work like before. Often the wireless connection seems disabled or doesn't respond even after restarting the computers. I manually disable it from the device manager and sometimes it doesn't work aswell. This problem is completely new and I have no explanation for it.

Do you think it is normal?

Thank you.
