As indicated by the figure above, the configuration we are trying to achieve here is very basic: it concerns two RUTxxx routers - RUT1 and RUT2. One functions as a PPTP Server, the other - a PPTP Client. They are connected into a virtual network via a PPTP Tunnel.

==Router configuration==


If you have familiarized yourself with the configuration scheme and have all of the devices in order, we can start configuring the routers using instructions provided in this section.


===PPTP Server (RUT1)===
==Introduction==
----
As mentioned in the prerequisites section, the router that acts as the '''server''' must have a Public Static or Public Dynamic IP address (more information on the subject can be found '''[[Private and Public IP Addresses|here]]'''). If that is in order, we should start configuring the server.
----
* Login to the router's WebUI and go to '''Services → VPN → PPTP'''. Select '''Role: Server''', enter a name for the new instance and click the "Add" button:

'''Point-to-Point Tunneling Protocol''' ('''PPTP''') is a Virtual Private Network (VPN) protocol that uses a TCP control channel and a Generic Routing Encapsulation (GRE) tunnel to encapsulate PPP packets.
----
* Click the "Edit" button located to the right of the newly created PPTP Server to enter the instance's settings window. The configuration is fairly simple, just remember to '''Enable''' the instance:

This article provides an extensive configuration example with details on how to create a connection between a PPTP Server and Client, both of which configured on RUTxxx routers.
----
* The rest of the parameters are user preferential so you should set them as you see fit. A short explanation on these parameters is provided below:
** '''Local IP''' defines the server's virtual IP address
** '''Remote IP range''' parameters define the range of virtual IP addresses that will be assigned to connecting clients
** '''User name''' and '''Password''' parameters define a client's authentication info
** '''PPTP Client's IP''' is used to assign a specific virtual IP to a specific client. It is not mandatory and, if left empty, the client will be assigned an IP address from the Remote IP range specified above


Once you're done setting these parameters don't forget to click the '''Save''' button.
==Configuration overview and prerequisites==


====Setting up a proxy (optional)====
Before we begin, let's overview the configuration that we are attempting to achieve and the prerequisites that make it possible.
----
'''Web proxies''' facilitate access to content on the World Wide Web and provide anonymity for the connecting clients. This is because the web proxy relays connected clients' requests through itself. Thus, the clients effectively "adopt" the server's Public IP address.
----
* If you plan on using the PPTP Server as a web proxy, you will need to edit one preexisting '''Zone Forwarding''' rule in addition to the server configuration. In the router's WebUI, go to '''Network → Firewall → General Settings''', locate '''pptp''' in the Zone Forwarding table and click the "Edit" button next to it:

'''Prerequisites''':
* Two RUTxxx routers of any type (excluding RUT850)
* A SIM card with a Public Static or Public Dynamic IP address for the PPTP Server
* An end device (PC, Laptop, Tablet, Smartphone) to configure the routers
----
----
* After this you will be redirected to the PPTP Zone Settings page where you will need to place a check mark next to the '''wan''' destination zone:

After you save the changes your PPTP Server will now also act as a web proxy.
As indicated by the figure above, the configuration we are trying to achieve here is very basic: it concerns two RUTxxx routers - RUT1 and RUT2. One functions as a PPTP Server, the other - a PPTP Client. They are connected into a virtual network via a PPTP Tunnel.


'''NOTE''': this step is purely optional and should be used only if you plan on using your server as a web proxy for your clients. If you are just planning to use PPTP to connect multiple remote networks into a single virtual network, you should probably skip this step.

===PPTP Client (RUT2)===

* Now let's configure the PPTP '''Client'''. Login to the router's WebUI and go to '''Services → VPN → PPTP'''. Select '''Role: Client''', enter a name for the new instance and click the "Add" button:

==Configuration overview and prerequisites==
----
* Click the "Edit" button located to the right of the newly created PPTP Client to enter the instance's settings window. In the settings window, '''Enable''' the PPTP instance, specify the server's '''Public (WAN) IP address''' and the '''client's authentication''' info as specified in the server's configuration:

* '''Optional''': if you plan on using the server as a web proxy, you should also enable the '''Use as default gateway''' option in the client's configuration:

==Testing the setup==
If you've followed the steps presented above, your configuration should be finished. But as with any other configuration, it is always wise to test the setup in order to make sure that it works properly. In order to test a PPTP connection, login to one of the routers' WebUIs and go to '''Services → CLI'''. Login with user name: '''root''' and the router's admin password. You should then be able to '''ping''' the opposite instance, i.e., if you logged in to the server's CLI, you should be able to ping the client's virtual IP address, and vice versa. To use a ping command, type '''ping <ip_address>''' and press the "Enter" key on your keyboard:
[[File:Configuration example l2tp pptp testing.png]]
If the ping requests are successful, congratulations, your setup works! If not, we suggest that you review all steps once more.
If you're using the server as a web proxy, end devices connected to the PPTP client router should have the Public IP address of the PPTP server. You can visit this website to check the Public IP address: http://www.whatsmyip.org/

Introduction

Point-to-Point Tunneling Protocol (PPTP) is a Virtual Private Network (VPN) protocol that uses a TCP control channel and a Generic Routing Encapsulation (GRE) tunnel to encapsulate PPP packets.

This article provides an extensive configuration example with details on how to create a connection between a PPTP Server and Client, both of which configured on RUTxxx routers.
