Connecting two routers different subnets.I still don`t get it.

[andreit]

Hello!

I attached a diagram with my setup.
I am trying to see the network from router B and i don`t know what i am doing wrong.

From router B i can go to 192.168.1.1 and see the router but i can`t see the network.

With static routing it s still not working.

Please give me a sugggestion.

Belkin = B?
ASUS = A?
Modem = M

Modem > Router A > Router B

B should be able to see network to A
A won't be able to see network to B due to NAT, unless you port forward.

If you remove the Modem and Internet. You can think of Network A as the internet and Network B as your home network.

Yes that`s correct.
Which ports should i forward?
And from B i can ping the router but i cannot see it as a network device.

Basically what i need is to see the printers from belkin in asus and in belkin to see the DLNA server from asus.

I don't remember the exact ports. You will have to search for those. Then you forward the required ports to the printers behind the Belkin Router (Using port forwarding on the Belkin).

So when you want to reach a printer from Network A you have to point the Client that wants to print to 192.168.1.123 which is the address on the WAN port of the Belkin router.

Automatic network discovery on Network A won't find devices on Network B.

Thank you,i understood and it makes sense.

But there is no alternative to see both networks as a whole?

 

[smakme7757]

Yes. Put the belkin in access point mode and connect it to the Asus with a cable from a lan port on the belkin to a lan port on the Asus. Dont terminate the first network to create a new one unless you want to for some specific reason.

That way everything would be on the same network and you get two WiFi access points to access it.

One of the main idea of Routers is to isolate networks.

In a way (out of Not being a big Networking maven) you are saying, ""I want to use two Routers (not same subnet) and see both networks"".

So in its basically sort of an Oxymoron.

There is ways to be able to see some aspects across Networks but it involved settings that make somewhat cumbersome to work.

So first, Why do you need two Router on two separate Subnets?

If it is Not for real Routing.

Using Wireless Routers (or Modem/Wireless Router) as a Switch with an Access Point - http://www.ezlan.net/router_AP.html

You could go on to each router and setup a static route for each subnet and enable redirected broadcasts for both routers 192.168.x.x networks but it will take active directory or something along the lines of that to advertise devices across network!

Thank you for the answers,i learned something from this.

I was thinking that one static route to the second router will do the job,but from what i understood a static route only points to the second network,it`s not connecting two subnets ).

But what about VLANs?From what i have read i understand the idea but how this technically works?
You must have two equipments that supports this service and configure two eth ports with the same vlan id ?

I played with DD-WRT and on some routers you can make some virtual interfaces bridging them to your physical interface but vlan seems something else.
