VPN using D-Link DIR-130

I  set up a VPN server using a D-Link DIR-130 connected to a cable modem. I am able to log in to the VPN remotely but I can not access any files in the server. What am I missing?

So far this are the steps I have taken :

1. I connected the DIR-130 to my cable modem.
2. I connected my server computer to a LAN port in the DIR-130.
3. I connected a DIR-655 to the DIR-130 (wan to lan) for my home network. I changed the private IP in this router to avoid conflicts with the address in the DIR-130.
4. In the DIR-130 setup page I created a VPN  using PPTP protocol.
5. In another computer I created a VPN client.
6. To test this arrangement I connected the computer with the VPN client to the LAN in the DIR-655 and logged in to the VPN, The connection was successful but I can not access any files in the server computer.

HELP!!!!!!!!!

Try connecting to the server by IP Address. Does that help?

Also try updating the firmware in the D-Link router?

And if all that fails, I found that a D-Link router at a client failed with ever newer XP and other OS updates and we had to change it for a different router.

Thanks for your reply. What do you mean by connecting to the server by IP address?

Also, I checked the firmware and its the latest available in D_Link's site.
When you try to access files on the other end, you do so by computer name or by IP address. That is what I meant. That is the first thing to try when you can connect but not see files. ... Thinkpads_User

I tried accessing a shared file using the IP address and could not opened it. I also tried to ping the server and got a "request timed out" message.

 However I searched for the computer using windows search and it located the computer and the file. It appears in workgroup Mshome under Microsoft Windows Network. I think this has nothing to do with the VPN and that it happened because I am using a computer connected to the DIR-655 router for my home network  which in turn is connected wan > lan to the vpn router. I placed the DIR-655 in the dir-130's dmz and thought it would not be considered part of this lan. I guess that may not be correct.

While following up on your suggestion I check my ISP and found that they do not allow port mapping.

"No. To offer exceptional service to all our customers, we do not permit residential customers to run servers of any kind. This includes but is not limited to PPP, FTP, HTTP, DNS, POP, SMTP, NNTP, PROXY, DHCP, IRC, TELNET, TFTP, SNMP and multi-user interactive forums, and remapping of ports for the purpose of operating a server on the network."

I guess this would be a problem in trying to run set up the VPN.?
Thank you.   I know VPN is difficult, and I was pleased to assist. .. Thinkpads_User

Just for educational purposes let's assume that my ISP did allow this types of connections. What settings would I have to change to make the VPN work correctly?

Would I have to access the gateways firewall setting and open the ports required for PPTP and IPsec?

Would I have to open any other ports to access the files residing in the server?

Afterward, how would I then access the server? Using the port forwarding feature in the D-LINK router to open the PPTP and IPsec ports and any other port to the server?

What services are needed to access shared files in the server? FTP?

Could I then use the firewall rule window to restrict access through the router only to authorized outside the LAN?

Finally, I read somewhere that a VPN service could be used to bypass some restrictions that internet providers may have in place. Do you think this may be a way to work around my problem?


Thanks and Happy 2011
