Speedify Firewall Overview
Speedify’s Firewall feature lets you block unwanted network traffic directly from within the Speedify app. With simple, destination-based rules, you can prevent connections to specific ports, IP addresses, or domains.
This feature is available on Unlimited accounts.
What Is the Firewall Feature?
The Firewall allows you to define rules that block outbound traffic from your device to specific destinations. Any traffic matching these rules will be stopped before it reaches its destination, regardless of which underlying connection (Wi-Fi, Ethernet, Cellular, etc.) Speedify is using.
Firewall rules apply while Speedify is connected and protect traffic across all bonded connections.
What Can You Block?
The Firewall supports three types of blocking rules:
Blocked Ports
You can block traffic to specific TCP or UDP ports, or entire port ranges.
Examples:
Block TCP port
25to prevent SMTP trafficBlock UDP ports
6881–6999to stop BitTorrent trafficOnce added, any traffic destined for those ports will be blocked.
Blocked IP Addresses
You can block traffic to specific IPv4 or IPv6 addresses.
Examples:
Block
192.168.1.100Block an external IPv4 address
Traffic destined for these IPs will not be allowed through Speedify.
Blocked Domains
You can block traffic to specific domains.
Examples:
example.comtracking.example.netAny traffic matching these domains will be blocked automatically.
How to Use the Firewall
Open the Speedify app
Go to Settings > Firewall
Choose what you want to block:
- Add a TCP or UDP port or port range
- Enter an IP address (IPv4 or IPv6)
- Add a domain name
The rule takes effect immediately while Speedify is connected.

Note:
- Firewall rules only apply when Speedify is connected
- Rules block outbound traffic to destinations
- Blocking rules apply across all bonded connections
