Hello! There is such a problem. My router is connected to another router. That other router gets the external IP and I don't have access to it to forward the port. a server is running on my computer on port 4545. Can I do something to get to my server from the Internet?

Ngrok service.

Answer 2

Fresh Zyxel Keenetic has the "KeenDNS via cloud" option, which allows you to access resources behind the router with only a gray ip on the external interface.
