VPNUK - The Virtual Private Network Specialists
The following instructions will guide you through a configuration of a PPTP or L2TP connection on a DD-WRT compatible router being used as an access point. There are hundreds of routers compatible with DD-WRT, please check the router database on the DD-WRT website for more information.
IMPORTANT NOTICE: VPNUK cannot assist in the flashing of, or installation of DD-WRT firmware, nor can we be held responsible for damage caused by clients configuring uncompatible routers. Please only install official DD-WRT firmware from the DD-WRT website onto compatible routers. Before you attempt to configure your router please setup a PPTP connection on your computer to ensure the account is working.
IMPORTANT: A 200MHz processor (most routers' processors) won't reach an optimal speed for some media related services when using PPTP. We strongly recommend all connections to the VPNUK servers over DD-WRT use the OpenVPN setup, its fast, stable and very secure.
1. Version Check
Login to your router with DD-WRT version v24-sp2 or higher on it.

2. Services
Click on the 'Setup' tab

3. Connection Type
Select 'PPTP' or 'L2TP' from the 'Connection Type' dropdown menu.

4. Use DHCP
If you chose 'PPTP' as the connection type place a check in the 'Yes' checkbox for 'Use DHCP'. L2TP does not have this option, you can move on to the next step.

5. Gateway Address
Enter the IP address of your VPNUK server in 'Gateway (PPTP Server) field'. The server details will have been sent to you in the Welcome email.

6. Login Details
Enter your VPNUK login username and Password into the 'User name' and 'Password' fields. These details will have been sent to you in the Welcome email.

7. PPTP Encryption
If you chose 'PPTP' as the connection type, place a check in the 'PPTP Encryption' checkbox. L2TP does not have this option.

8. STP Settings
Ensure the STP checkbox is set to 'Disable'.

9. Local IP address
Enter an IP address for the DD-WRT access point.
NOTE: You need to choose an IP that will not not conflict with your main routers IP address. For example, if your main router is 192.168.1.1, you can make the access point something like 192.168.1.51 - You would then have to use that IP address to login to the DD-WRT administration area once you have applied the changes..

10. Subnet mask
Set the 'Subnet Mask' to '255.255.255.0'.

11. Enable DHCP server
Ensure the 'DHCP Server checkbox is set to 'Enable' and the 'Start IP Address' is higher than the DD-WRT Routers, 'Local IP Address'.
Note: You can leave the static DNS on 0.0.0.0 if you wish to use your default DNS servers. If you have problems with your ISP hijacking your DNS, you can change the Static DNS to Google DNS by entering DNS 1 as 8.8.8.8 and DNS 2 as 8.8.4.4

12. DHCP & DNS Settings
Uncheck all three checkboxes for 'Use DNSMasq for DNCP', 'Use DNSMasq for DNS' and 'DHCP-Authoritative'.

13. Save the Setting
Click the 'Apply Settings' Button.
Note: If you changed the IP address of the DD-WRT router in part 9 the DD-WRT administration area will be at that URL once the settings have been applied. You will have to login to that new IP address in order to continue with the DD-WRT setup after clicking the 'Apply Settings' button.

14. Security Settings
Click on the 'Security' button in the menu at the top of the page.

15. Disable Firewall
Select the 'Disable' checkbox in the SPI Firewall.

16. Apply Settings
Click onto the 'Apply Settings' button in order to save the changes.

17. VPN Passthrough
Click onto the 'VPN Passthrough' button.

18. PPTP Passthrough
Ensure the 'PPTP passthrough' button is set to 'Enable'.

19. Apply Settings
Click onto the 'Apply Settings' button in order to save the changes.

20. Complete Setup
Click onto the 'Administration' button.

21. Reboot DD-WRT
Scroll down to the bottom of the page and click on the 'Reboot Router' button.
Note: It's a good idea to reboot your main router also.

21. Check connection
If you have not already done so you must connect your DDWRT router WAN port to your modem or to the LAN port on your main router.
22. That's It
Your DD-WRT router will now reboot. Once rebooted you should be connected to the VPN. You can check this from the Status -> WAN tab or by going to a site like: whatismyipaddress.com.
Note: If the 'Login Status' says 'Disconnected' click onto the 'Connect' button and wait for about 10-15 seconds for the VPN to connect.
