# Fantasy Grounds - Port Forwarding and a "transparent" OpenVPN setup

{% hint style="info" %}
This document, initially written in June 2019 for FG "Classic", is now being updated (September 2020) for :

* **simultaneous** GMs/games through a **single VPN server for FGC/FGU/FGC+FGU**
* **FG "Unity" hosting games in LAN mode**

For these use cases, specific sections have been added before appendixes.
{% endhint %}

**FGU = Fantasy Grounds Unity** vs. **FGC = Fantasy Grounds Classic :**

With **FGU**, hosting a game in **"Cloud" mode** should be **ok for all GMs**, whatever their specific network situation, **without needing any kind of VPN**.

However, if for any reason (platform unavailable, broken Internet routes, privacy concerns, whatever...) you want to host an **FGU** game in **LAN mode** :

* it is the same kind of networking topology and constraints as FGC
* the **default** protocol/port for **FGU** is **UDP** 1802 while **FGC** uses **TCP** 1802

{% hint style="info" %}
Most of what I wrote in this document for **FGC = FG "Classic" (and the TCP protocol)** can be transposed to **FGU = FG "Unity"** hosting in **LAN mode (and the UDP protocol).**
{% endhint %}

{% hint style="success" %}
**FGU** game hosting in **CLOUD mode should** be totally straightforward in all networking situations and **not require any kind of port forwarding or VPN** (except if some countries block traffic to the Unity servers...)
{% endhint %}

This document will describe a solution for GMs (Game Masters) to publish their Fantasy Grounds virtual table to remote players through an ad-hoc "GM-only" VPN, hosted on a small AWS (Amazon Web Services) Linux server.

***But first...***

## Do you *really* need a VPN for <img src="/files/-LhuxHlumVaJRYKa19gU" alt="" data-size="line"> Fantasy Grounds "Classic" <img src="/files/-LhuxHlumVaJRYKa19gU" alt="" data-size="line"> ?

{% hint style="success" %}
**Most GMs do not need to use a VPN** to successfully share their virtual table for players
{% endhint %}

{% hint style="success" %}
**Players generally do not need to use a VPN**
{% endhint %}

There are however situations where **a VPN may be needed on the GM's side** :

1. **temporary connection from a "public" internet facility** (hotel room, etc)
2. country/ISP setup makes a **unique public IPv4 address unavailable**
3. **proper port forwarding not possible** for one (or more) router(s)
4. **upstream "closed" firewall**

{% hint style="warning" %}
Also : **if you are a player and your GM is using a "closed VPN" offer like Hamachi, you will have to be a member of the same VPN as the GM to join the game.**
{% endhint %}

{% hint style="success" %}
This document presents a **"transparent" VPN solution**, where :

* **only the GM** uses the VPN
* the VPN is used to **forward FG traffic only** (TCP 1802)
* the **players do not have to install/use any kind of VPN** or custom IP routing software
  {% endhint %}
