Question based on a solved question I made before: How to connect computers to a network printer behind a router?

General question:

How to access shared folders of computers separeted by a router?

Particular question:

How to access shared folders from C-3 using C-1 or C-2 computer and vice-versa?

What? Where?

            [ISP]
              |
              | -> IPs:200.X.X.X/other configs:DC

            [R-1]
              |
              | -> IPs:10.1.X.X locked by MAC,M:255.0.0.0,G:10.1.0.1

 [PRI] IP:10.1.7.7    [R-2] IP: 10.1.0.1,MAC:A    [C-3] IP:10.1.7.8
                        |
                        | -> IPs:192.168.1.X,M:255.255.255.0,G:192.168.1.1
            |¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯|
            |                      |
          [C-1] IP:192.168.1.2   [C-2] IP:192.168.1.3,MAC:A

Glossary and details:
------------------------------------------------------------------------------------
- IP: IP.
- IPs: Some IP range.
- M: Mask.
- G: Gateway.
- MAC:A: A MAC address that I will not inform you :)
- DC: Don't care.

- ISP: Internet Service Provider (not so much details about it on that case).
- R-1: A real router or some concatenated so IP range bellow that block is 10.1.X.X
       and above is ISP. The provided IPs are provided by MAC. As all available
       addresses are in use, you must clone an existing one to join with a new
       device (and to disconnect the cloned one).
- PRI: An network printer (some people here call that IP printer).
- R-2: A TP-LINK TL-WR340G, mine wireless router (since my computer does not have
       ethernet input, it is my ethernet-wifi adapter :), admin access, MAC address
       cloned from C-2 (MAC:A). I've to configure 10.0.1.1 and 10.0.1.2 as DNS
       addresses, other wise I cannot connect C-1 and C-2 to Internet.
- C-1: My computer, a CCE XLE-425 (remember: no ethernet input), with Windows 7,
       admin access.
- C-2: another computer with better configs than mine, MAC:A, Windows XP.
- C-3: another computer, Windows XP

Requirements:

I want to continue printing normally, as in solution of mentioned solved question (I redirected 9100 and 9101 port traffic to computers C-1 and C-2 respectively), to access Internet and to do it myself (no need to call network admin men in black people).

I would like to access shared folders as easy as using \\C-1, \\C-2, \\C-3 or \\x.x.x.x and te name of shared folder, as in common sharing...

Pay attention to MAC clones and DNS info.

What I think that can solve the problem:

Well, in mentioned solved question, I redirected ports related to IP printer to computers I wanted to use it. I think redirecting ports to correct ones - I don't know which ones - solves that too...

Try to see if this works http://pigtail.net/nicholas/tp-link/
Note: The WAN port will not be used. This is normal for some models.
Note 2: Before I rewrite/write this link to be included in the answer, I would have to verify that it works.

networking - Adding router to existing wireless network to separate networks

networking router wireless-bridge bridge-router

I just moved into an apartment complex which offers free wireless internet for all tenants. They use Meraki wireless devices and to my surprise the internet access has been very stable in the short time (1 week) I have been in this apartment.

That's all great for one computer connecting to the internet, but I have two laser printers, three VoIP phones and other networking equipment which needs to be on a LAN. The printers don't even need internet access.

I want to add a router to separate my local network from their huge wireless 'cloud'.

this would allow me to connect to my printers and only hit their wireless network when I wnat to access the internet. I have already been told they could 'whitelist' a MAC address, so they could do that for either my Router or my Wireless Bridge - not sure how that would work. Please advise. Basically I want to know if it works like this:

Wireless/Meraki ))
    )) Linksys WET54G Wireless Bridge 
          -----| WRT54GS Router
                   > Device 1
                   > Device 2
                   > Computer 1
                   > Computer 2

If that little diagram doesn't make sense, I am basically trying to do the following:

Connect Linksys WET54G (Wireless Ethernet Bridge) to existing Meraki Wireless Network
Connect the cat5 cable from the wireless bridge into the router
Connect all of my devices into that router so I can have a lan. If I want to print, I don't have to send a 50MB document over some wireless mesh.
