• Enable NAT: Ensure that Network Address Translation (NAT) is enabled on the EasyTether interface, allowing pfSense to properly route traffic.
• Optimize DNS Settings: Use a fast, reliable DNS provider like Google DNS (8.8.8.8) or Cloudflare DNS (1.1.1.1) for better performance.

8. Security Considerations

Using mobile data as an internet connection can expose your network to security risks, especially if you’re using public or unsecured mobile networks. Here are some tips to secure your EasyTether setup:
