Connectivity across multiple subnets configuration issue

Hello, everyone!

I have a (hopefully) quick question. I am helping my church with getting a printer to be "visible" across the network.

Here's how it's set up:

ISP box
|
ISP firewall
|
ISP-controlled DHCP server (192.168.0.1)
|
4 different wireless routers directly connected to this server, spread about the building to maximize signal strength:
Router 1: 192.168.2.1
Router 2: 192.168.3.1
Router 3: 192.168.4.1
Router 4: 192.168.6.1

As you can see, these all run on separate subnets w/ no non-typical masking (all 255.255.255.0).

The printer is connected wirelessly to Router #1 (192.168.2.1). The IP assigned to it is 192.168.2.50. When I try to ping it from any router other than Router #1, I get "Destination net unreachable" (windows). How do I fix this?

Routers 1-3 are Netgear WNDR3500Ls, and the 4th router is a Netgear WNDR4500L.

Any help in this would be greatly appreciated; I'm pretty clueless here.

Thanks!
Alex

Very complex to fix using those type routers.

You main problem is the nat. Just like you must port forward on the internet you must port forward the printer. You should be able to forward the 192.168.0.xx wan address of the router to 192.168.2.50. Then the other machines can access it using the ip 192.168.0.xx

This of course gets to be a huge pain if you more than just a couple of these.

A simpler configuration would be to move everything to the same subnet. You may have to make it bigger if you have more than 250 devices. You would set all your router to act as AP instead of router.

A second option if main router supports it is to move the gateway for each of these subnets to the main router on a different vlan. You again set the other router to AP mode. The main router if it understands vlans will also be able to directly route between them.
