Guide to Configuring Limited Bandwidth in SECUI Bluemax NGF

In a corporate network environment, bandwidth management is not just a technical task, it’s about ensuring performance and user experience. When one department consumes excessive bandwidth, other teams may struggle to access essential services smoothly. That is why the bandwidth limiting feature or QoS (Quality of Service) in Next Generation Firewall such as SECUI Bluemax NGF must be utilized.

If you’re looking for a quick and effective way to configure limited bandwidth in Bluemax NGF, this guide will walk you step by step through the process.

1. Test Internet Speed

Before configuring bandwidth limiting in Bluemax NGF, it’s best to check your internet speed first. The results will serve as a reference when setting the bandwidth limit later.

2. Log In to Bluemax NGF

Open your browser and log in to the Bluemax NGF web interface using an account with configuration privileges.

3. Navigate to QoS Profile Settings

Once logged in, go to:

Security Policy > QoS > QoS Profile Settings

Figure 3.1 QoS Menu

Here you’ll create the main QoS profile. This is a crucial step in firewall QoS configuration. Click Add.

Figure 3.2 QoS Profile Settings

In the Add Profile form, fill in the details:

• Transmission Limit Bandwidth: Adjust according to your main network bandwidth.
• Profile Type: Select Firewall QoS Profile.
• Profile Name: e.g., Limited Bandwidth.
• Click OK.

Figure 3.3 Add Profile

It’s recommended to match the limit with your existing bandwidth, as this will become the default for all users.

4. Add a Queue (Bandwidth Allocation)

Go to the Queue menu to configure bandwidth details, then click Add.

Figure 4.1 Queue Name

Fill in the parameters:

• Enter the bandwidth limit according to your needs.
• Click OK.

This queue will later be attached to your firewall policy, which is a key step in firewall bandwidth management.

5. Add a Firewall Policy

Navigate to:

Security Policy > Firewall > IPv4 Firewall Policy

Then select the policy where you want to apply the bandwidth limit.

6. Create QoS Policy Settings

Go to: Security Policy > QoS > QoS Policy Settings

Figure 6.1 QoS Policy Settings

Click Add, then configure the parameters:

• Control Target: Select System.
• Profile: Choose the QoS profile you created earlier.
• Click OK and check Execute (Enable) to activate.

7. Test and Monitor

After activation, test internet speed again from a user’s perspective. You should notice a significant difference in line with the bandwidth restrictions.

For further monitoring, go to: Analysis > System > QoS Analysis

Conclusion

Configuring limited bandwidth in Bluemax NGF not only stabilizes your network but also ensures fairness across all departments. Everyone gets a fair share of the connection, preventing bandwidth monopolization by a single heavy user.

This firewall bandwidth management setup is simple: create a profile, configure a queue, attach it to a firewall policy, then enable and monitor it.
