You are home but still want to be able to access servers, share files, pick office calls, print to a printer in your office, then what you need is a remote access VPN. What better way to have it configured than on a Mikrotik router. One of the best things that have happened to home office/small office (SOHO) is Mikrotik. Take it from me and am not saying this because of the complexity involved when setting up a Cisco gear;I am a Cisco professional. Mikrotik has made it possible for you to have a wireless outdoor radio with full routing functions, firewall and VPN capabilities all wrapped into one very inexpensive box,plus, it is very easy to configure. What more can you ask for.
Anyway,my aim here is to show you how to set up a remote access VPN using ANY Mikrotik router with a PPP function. Here we go.

Make sure all the basic configurations needed for your router to access the internet have been entered, have at least one public IP address for users to dial up to. Having done these little things,lets begin. Follow the steps outlined in the pictures below:
In the first picture, Click on PPP,then under the profile tab,enter a name for the profile, enter the local address on the router's LAN interface that connects to the network you want clients to access remotely,enter an address from your network that you want given to the user upon successful connection. If you have more than one client connecting to your VPN server at a time, create a pool and use the pool instead. Apply and ok.
Next step in the second picture: under the secret tab, enter a username for clients, enter password, choose the profile created in step one above, service should be set to PPTP or ANY. Apply and ok
In the third picture, under the interface tab, click on pptp server, in the window that appears, click on enable, choose the profile created in step one. Apply and ok.
Then in the fourth picture, click on the LAN interface you configured your VPN for and choose proxy-arp. Without doing this, your VPN clients will connect be will not be able to communicate with any device on the LAN. This is where the configuration ends. To connect to the VPN from a windows 10 computer, where is what you need to do:Am using Windows 10. To connect, go to network and sharing centre, click on set up a new connection or network (your computer MUST be connected to the internet) click on connect to a work place, click on no,create a new connection,click next, click on use my internet connection, enter the public address on your VPN server, and following the rest steps;it is easy.
