By utilizing parental control features, you can create a safer online environment for your family members and protect them from inappropriate content.

VPN (Virtual Private Network) Passthrough

If you use a VPN (Virtual Private Network) to enhance online privacy and security, your Xfinity router may include a VPN passthrough feature. VPN passthrough allows VPN connections to pass through the router's firewall without being blocked. To enable VPN passthrough on your Xfinity router:

• Access the router's configuration page.
• Look for the "VPN Passthrough" or "VPN Settings" section.
• Enable the VPN passthrough option for the desired VPN protocol (e.g., PPTP, L2TP, IPSec).
• Save the settings to enable VPN passthrough.

Enabling VPN passthrough ensures that your VPN connections remain secure and uninterrupted while using your Xfinity router.

Guest Network

Your Xfinity router may offer a guest network feature that allows you to create a separate network for guests or temporary users. This helps to ensure that guests do not have access to your main network and preserves its security. To set up a guest network on your Xfinity router:

• Access the router's configuration page.
• Look for the "Guest Network" or "Guest Wi-Fi" section.
• Create a new guest network by specifying the network name (SSID) and password.
• Save the settings to enable the guest network.

By utilizing the guest network feature, you can provide internet access to guests without compromising the security of your main network.

Conclusion

Changing the firewall settings on your Xfinity router is a crucial step in enhancing the security and customizing the network access of your home network.
