Help with wireless routed network

Hi

I was hoping for some help setting up my home network...Here is the situation:

Internet cable broadband > Netgear vmdg280 Wireless router

The Wireless router works on the 192.168.1.0/24 subnet.

This works fine.

But, I have an HP server running a couple of VM's in the upstairs loft. The VM Host and the VM guests are on the 192.168.1.1/24 subnet. I have a dg834G Netgear Wireless router up there too.

I would like to be able to access both my VM's and the Internet from a laptop that is connected over WiFi.

I assume to be able to do this, I need to have some sort routing between the two Wireless routers. Does anyone know if this is possible and, if so, how I can do this?

Well the first problem that you have is that 192.168.1.0/24 and 192.168.1.1/24 describe the same subnet, i.e 192.168.1.x.  You need to give your db834g a different subnet such as 192.168.2.0/24.

Not familiar with the netgear, but I would guess it is much like any consumer grade router.  Give your dg834G a static 192.168.1.x address on the "external" interface and have it route for 192.168.2.0/24 on the "internal" subnet.  Your VM addresses will be on the 192.168.2.x network.  Then on the same router find where you specify static routes and give it a default route pointing to the 192.168.1.x (probably .1) address of the vmdg280 router.

Now on vmdg280 create a static router for your 192.168.2.0 255.255.255.0 network and point it to the "external" 192.168.1.x address on your dg834G router.

That should do it.

Hi JDavis,

Sorry, there was a typo in my original message.

The Wireless router works on 192.168.0.0/24 subnet, sorry.

The VM works on 192.168.1.0/24 as mentioned.

Do the instructions still apply?

Yes, same instructions.

Hmmm, doesn't seem that straightforward on the Netgear, although I do understand what you're saying.

Any Netgear experts out here?
You actually can't do this completely wirelessly, since the "external" or "wan" port of the router upstairs needs to connect to the downstairs router by cable. So if you can run a cable, then you can do the above. Otherwise, it sounds like you need to use a wireless bridge/repeater upstairs, and would most likely have to change that subnet to the main one downstairs.

I found a manual for the dg834G, but it appears the VMDG280 is a box made specifically for Virgin Media and it is supported by VM.  It doesn't appear that they made a manual available.  I did see one post where someone was doing what you are attempting to do, and it stated that he specified the internal router/network as a DMZ.

The DG834G manual can be found at the link below.  Static routes are described on page 7-10.

As to the post above, I did not read in your post that you were trying to do this over wireless.  The DG834G is connected to the VMDG280 with a cable, correct?

Hi All

>"The DG834G is connected to the VMDG280 with a cable, correct?"

Nope, that's the thing. There is no wired connection between the two, I was hoping to do all this wirelessly?

Since this is not possible to do completely via wireless unless the specific router/bridge can be placed in wireless access point (or cables used), I think my comment 33942818 should be the "solution".
