How do I connect to my country-house router and cameras via a SIM card without a public IP?

VIA PEER-TO-PEER (P2P) NETWORKS LIKE TAILSCALE OR A REVERSE TUNNEL.
When incoming ports are blocked by the carrier, traditional port forwarding won't work. Special software forces both devices to connect from the inside out through a cloud authentication server.

How Port Punching Works

Instead of making a direct call to the modem, connection is initiated from the inside: both your remote phone and the country-house router send outbound packets to a shared secure coordinator. This establishes a secure virtual local network directly between devices, bypassing any closed ports of your mobile provider.
