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...

Port redirection configures a "Many-to-One" relationship. You need "Many-to-Many" inorder to achieve this, routing. So port redirection won't work in this matter. Does R-2 has a routing config as "dest:10.0.0.0 mask:255.0.0.0 gateway:10.1.0.1" and R-1 has as "dest:192.168.1.0 mask:255.255.255.0 gateway:10.1.0.1" ? –  The_aLiEn Jul 26 '12 at 20:41
    
No and I don't know how to perform something like that :) –  kokbira Jul 27 '12 at 17:30

Change wireless router from NAT to a bridge (Non DHCP; Many-to-Many) :) What is the model name and number on your wireless router? –  Diblo Dk Jul 7 '13 at 13:29
    
It is a problem, because I could not see how to change TP-LINK TL-WL440G to bridge mode :( –  kokbira Jul 7 '13 at 13:33
    
Do you have a link to the manual. I do not get any results on google? –  Diblo Dk Jul 7 '13 at 13:36

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.

Very good! I'll test today, but I'm accepting your answer. –  kokbira Jul 8 '13 at 13:49
