Can't connect to gameserver over self hosted Reverse Proxy Server

Hello Guys,

I am running a home server and some applications I host to the
Internet. Now I want to enhance the secruity of my network and started
to proxy my applications, such as a selfhosted 2FA and a search engine
through Cloudflare, which works fine for these kinds of applications.

But as I tried to proxy a gameserver through Cloudflare, I found out,
that Cloudflare only supports proxying through certain ports, and
Server-Ports like Factorio or Minecraft (34197, 25565) are not
supported in the free Plan.
At the moment, I have an SRV record in place which redirect incoming
traffic from [games.example.com](https://games.example.com) over the
right port to my gameserver. But that's not a permanent solution I
want to use and it is just pointing at my home ip, so not the safest.

My Idea then is, rent a small vServer, install a Reverse-Proxy like
NginxProxyManager and establish a secure VPN connection with Wireguard
between my gameserver and my selfhosted Reverse Proxy.

The connection is working and when I check my Gameserver's IP, when
I'm connected with the VPN, I have the IP of my rented server. But I
can't get a connection to my Gameserver. I attempted it with the
domain, with the IP of the rented Server with and without the RP
running but I cant get to my gameserver.


That's my wg0 config for the Proxy/Rent Server:

`[Interface]`

`Address =` `10.0.0.1/32`

`SaveConfig = true`

`PostUp = iptables -A FORWARD -i wg0 -j ACCEPT; iptables -t nat -A
POSTROUTING -o eth0 -j MASQUERADE`

`PostDown = iptables -D FORWARD -i wg0 -j ACCEPT; iptables -t nat -D
POSTROUTING -o eth0 -j MASQUERADE`

`ListenPort = 51830`

`PrivateKey = `

​

`[Peer]`

`PublicKey = `

`AllowedIPs =` `10.0.0.2/32`

`Endpoint = ip of my homenetwork:port`

and for the Client/gameserver:

`[Interface]`

`PrivateKey = `

`Address =` `10.0.0.2/24`

​

`[Peer]`

`PublicKey = `

`Endpoint = proxy``:``51830`

`AllowedIPs =` `0.0.0.0/0`

`PersistentKeepalive = 25`

The Proxy Manager is working but I couldn't figure out, what the right
settings are, that if someone wants to connect to my gameserver via
[games.example.com](https://games.example.com) , that the PM routes
the traffic trough the Wireguard Tunnel to my gameserver.

My Webhoster told me, the ports on the Server are not restricted, so
there shouldn't be a blockage either.

If anyone has an Idea on how to get it working with this setup or has
a different approach, please let me know.

Reverse proxy servers typically proxy web services (things like
websites, over HTTP/HTTPS/TCP etc).

Gameservers are not the same as a website.

You should ask subs that are specific to the actual game if someone
has made a tool that works with that game, or in a rare case, if a
specific existing reverse proxy can be made to work with it.

As thekrautboy said gameservers are not the same as websites so a web
proxy does not work.

You'll need a game specific proxy.
I've used https://github.com/haveachin/infrared for Minecraft with
success but that was on the same docker network
