Not able to host server with Zero Tier

[Nitrozbox]

Hi,

So, my friends decided to play custom maps in Rocket League and according to Lethamyr's guide to set up custom maps(How to Set up Custom Maps — Lethamyr) we did all the steps and connected to one's hosted server. Now, the problem is that everyone is able to host the server/game except me and I am the only one using Airtel Xstream from the bunch.

So, just wanted to know if there are any restrictions from Airtel's side that I am not able to host the server.

P.S. We all are using the same network that one us created.

Since airtel has public IP you don't even need zerotier. Just host and forward the port from router to your PC and open the firewall on your PC.
Although zerotier requires some significant amount of config. For creating a mesh based VPN setup I would suggest tailscale, it is as easy as and just installing an application and you are ready to go.
