VPN pfsense to pfsense to open ports on a ISP that does not allow for any open ports

Last setup and tested: 10-21-2018

Why did I (sesipod) need to do this ?

I need to use this to open ports on my home internet connection. I use a service provider that offers home internet over 4GLTE and they do not allow for Static IP addresses or ports to be opened. So this is the way that I am getting my web servers and plex online to the world.

You can also use this setup if you would like to send all of your home internet traffic over the VPN so that your isp can't see your data.

Before we begin

You are going to need a few things….

  1. A network with pfsense router version 2.4.4
  2. A VPS server with pfsense installed version 2.4.4
  3. About 30 min of time.

I am going to be using a VPS form a provider called VULTR. It costs $3.50 per month and is the best deal for this project.

  • CPU: 1 vCore
  • RAM: 512 MB
  • Storage: 20 GB SSD
  • Bandwidth: 500 GB

The basics

  1. Setup a pfsense to pfsense point to point openvpn connection.
  2. Setup and make sure that the VPS pfsense can ping the home LAN.
  3. Setup the vpn client as a VPN Interface.
  4. Setup the vpn Interface as the primary Gateway.
  5. Setup outbound NAT for LAN so that all devices use the WAN gateway.
  6. Setup outbound NAT for an alias list of devices to use the default (VPN) gateway.
  7. Setup Firewall RULES so that traffic can be directed to the correct location.

Configuring VPS pfsense

We need to now configure pfsense for use. Lets start by opening your web browser and entering the ip in the address bar like so: . I am going to be using google chrome for this part.

  1. Chrome will complain about the page not being secure. This is normal press Advanced Then Proceed to {IP} (unsafe). The reason this is happening is because pfsense is using a self signed certificate.
    • cdn.sesipod.info_sesipod.info_pf-vpn-pf-ports_pg1_pf-vpn-pf-ports-23.jpg
  2. You should be at the login page now. The default username and password will be admin / pfsense.
    • cdn.sesipod.info_sesipod.info_pf-vpn-pf-ports_pg1_pf-vpn-pf-ports-24.jpg
  3. After login you should be here now. Click on Next.
