Speedify Firewall Overview

This article explains what the Speedify Firewall feature is, what you can block with it, and how to set it up in the Speedify app.

What Is the Speedify Firewall Feature?

The Speedify Firewall lets you create rules that block outbound internet traffic from your device to specific destinations. Any internet traffic that matches one of your rules is stopped before it reaches its destination, regardless of which underlying connection (Wi-Fi network, Ethernet, 4G/5G cellular connection, etc.) Speedify is using at the time.

Firewall rules are active while Speedify is connected and apply across all bonded connections simultaneously.

What Can You Block?

The Speedify Firewall supports three types of blocking rules.

Blocked Ports

You can block internet traffic to specific TCP or UDP ports, or entire port ranges.

Examples:

• Block TCP port 25  to prevent SMTP internet traffic
• Block UDP ports 6881–6999  to stop BitTorrent internet traffic

Once a port rule is added, any internet traffic destined for that port will be blocked.

Blocked IP Addresses

You can block internet traffic to specific IPv4 or IPv6 addresses.

Examples:

• Block 192.168.1.100  to prevent connections to that local address
• Block an external IPv4 address to cut off a specific remote server

Internet traffic destined for those IP addresses will not be allowed through Speedify.

Blocked Domains

You can block internet traffic to specific domain names.

Examples:

• example.com
• tracking.example.net

Any internet traffic matching these domains will be blocked automatically.

How to Use the Firewall

Step 1

Open the Speedify app and go to Settings > Firewall.

Step 2

Choose the type of rule you want to add, then enter the relevant value:

• A TCP or UDP port or port range
• An IP address (IPv4 or IPv6)
• A domain name

The rule takes effect immediately while Speedify is connected.

• Firewall rules only apply when Speedify is connected.
• Rules block outbound internet traffic to destinations.
• Blocking rules apply across all bonded connections.
• This feature is available on Unlimited accounts only.
