How to release a router on the Internet?

Question

ASUS

Good afternoon, I ask for help in network configuration, I have an ASUS RT-N12VP router with tomato firmware.
The router receives the address 10.65.80.50, I need to forward the ports out to the Internet in order to show people the project that I messed up =)
How can I release the router to the Internet?

Answer 1

Good day.
You seem to be behind an ISP NAT, so it won't work directly.
As an option - buy the cheapest VDS and set up an OpenVPN server, install a client and configure routing on the server. On the router, you will have to forward the port the same.
Or some tunnel broker, raised IPV6 over IP4 + CloudFlare and domain.
