Firewall Configuration for Shiny + HTTPS

This script enables incoming traffic on ports commonly used by NGINX (HTTPS) and Shiny Server:

• Port 443: Standard HTTPS traffic (handled by NGINX)
• Port 3838: Shiny Server application traffic

Usage

Run the script with:

chmod +x allow-shiny-ports.sh
./allow-shiny-ports.sh

Make sure to run it as a user with sudo privileges.

Result

This will: - Allow TCP traffic on ports 443 and 3838 - Save these iptables rules persistently via netfilter-persistent
