🐧 GRE Tunnel - For DDoS Protection

I need some kind of help. I need to do GRE Tunnel for my Windows Server to protect my Game Server.

I tried to follow many tutorials but they are outdated and don't work anymore.

So I will explain here what I need to do: (Example)

Windows Server IP: 111.111.111 OVH VPS IP: 222.222.222

So I need my Windows Server to send this information to VPS:

​

• 111.111.111:2302
• 111.111.111:2402
• 111.111.111:2312
• 111.111.111:27016

(This done on Windows Firewall right?)

After I need my OVH VPS to send the same information to my Windows Server:

​

• 222.222.222:2302 UDP-TCP
• 222.222.222:2312 UDP-TCP
• 222.222.222:2402 UDP-TCP
• 222.222.222:2716 UDP-TCP

This is for a Game Server

I really need help on which commands I need to run because I'm super lost.

I'm sorry if this is not the correct place.
