Subnet¶

Note: This page is currently available on Flint 4 (GL-BE14000), and will be rolled out to other models with firmware v4.10.

On the left side of the web Admin Panel, go to NETWORK -> Subnet.

The page consolidates the configuration of LAN, Guest Network, IoT Network, and custom VLAN Networks into a single unified view. It provides a centralized management interface for all subnet-related settings, allowing you to create and manage multiple subnets to isolate different types of devices or traffic.

Main Network¶

Main Network is the network that your device is connected to via the main Wi-Fi or via an Ethernet cable.

In the Main Network, you can directly view all interface statuses, VLAN ID, router IP address, and DHCP Range.

main network 1

Click Edit in the lower-right corner to configure the Main Network.

main network 2

The configuration page includes Basic settings, DHCP server settings and Address Reservation.

Basic Settings¶

You can set the subnet within the IPv4 private address ranges: 192.168.0.0/16, 172.16.0.0/12, 10.0.0.0/8

main network basic settings

Router IP Address

This is the address that you would enter into your browser's address bar to access the router's admin page.

It is 192.168.8.1 by default. You can change it if it conflicts with your network.
Netmask

Defaults to 255.255.255.0. You can also select 255.255.0.0 if you need a larger subnet with more IP addresses.
VLAN ID

The Main Network's default VLAN ID is 1, which cannot be modified.
AP Isolation

You can isolate client devices into a separate network segment. These devices will not be able to communicate with other devices on the same network.

DHCP Server¶

The DHCP Server is enabled by default. The DHCP server automatically assigns IP addresses and other communication parameters to each client devices.

If the DHCP server is disabled, you will need to configure network settings for client devices manually. Click here to learn how to manually configure a static IP.

You can change the starting and ending IP addresses to suit your needs — for example, if your network expands or shrinks, if IP address conflicts occur, or if the subnet mask range is modified.

Lease Time: The period for which a DHCP-assigned IP address is valid for a device.
Gateway: The device that routes traffic between the local network and external networks such as the Internet.
DNS Server: Two DNS server fields are available for configuring the primary and secondary resolvers.

Note: The primary DNS is entered in the upper field, and the secondary in the lower field. In the event of primary server unavailability, client devices will automatically failover to the secondary resolver, ensuring domain name resolution continuity.
LPR Server (Line Printer Remote Server): A service that manages print jobs and allows network devices to send print requests to remote printers. Multiple LPR printer ports can be configured.

Address Reservation¶

When you specify a reserved IP address for a client within the LAN, the client always receives the same IP address each time it accesses the router's DHCP server. You can assign reserved IP addresses to computers or servers that require permanent IP settings.

Note: Configured clients have to reconnect the router to activate.

Click Add to reserve an IP.

main network address Reservation 1

You will see a pop-up window.

main network address Reservation 2

Select MAC from the dropdown list. The corresponding available IP will be auto-filled. You can optionally enter a hostname and a custom name for easy identification. Then click Submit.

main network address Reservation 3

After adding a new IP address reservation, you will get the page as shown below, which means you have set it up successfully.

main network address Reservation 4

Guest Network¶

The Guest Network provides a dedicated Wi-Fi network for visitors. Isolated from the primary network, it enhances security while providing convenient internet access.

Note: Some models (e.g., GL-MT5000, GL-MT2500/GL-MT2500A) do not have Wi-Fi functionality, thus the Guest Network settings are not available on their web Admin Panel.

In the Guest Network, you can directly view the interface status, VLAN ID, Gateway, and DHCP Range.

guest network 1

Click Edit in the lower-right corner, and the Guest Network configuration panel will open on the right side of the page.

guest network 2

The configuration page includes Basic settings and DHCP server settings.

Basic Settings¶

You can set the subnet within the IPv4 private address ranges: 192.168.0.0/16, 172.16.0.0/12, 10.0.0.0/8

guest network basic setting

Gateway

The default gateway of the Guest Network is 192.168.9.1. If it conflicts with your local network, change it to a different one.
Netmask

Defaults to 255.255.255.0. You can also select 255.255.0.0 if you need a larger subnet with more IP addresses.
VLAN ID

The Guest Network's default VLAN ID is 9, which can be modified as required.
AP Isolation

This feature has been available since firmware v4.5

You can isolate client devices into a separate network segment. These devices will not be able to communicate with other devices on the same network.
WAN Access Control

WAN Access Control manages local subnet access to WAN-side networks, including the internet and other WAN subnets.

Three WAN access control modes are available:
- Unrestricted: Allows this subnet to access the internet and other WAN-side subnets without restrictions.
- Block WAN Subnet: Blocks access to other WAN-side subnets. Internet access remains available.
- Block Internet Access: Blocks all outbound access, including the internet and WAN-side subnets.

DHCP Server¶

The DHCP Server is enabled by default. The DHCP server automatically assigns IP addresses and other communication parameters to each client devices.

If the DHCP server is disabled, you will need to configure network settings for client devices manually. Click here to learn how to manually configure a static IP.

You can change the starting and ending IP addresses to suit your needs — for example, if your network expands or shrinks, if IP address conflicts occur, or if the subnet mask range is modified.

LPR Server (Line Printer Remote Server): A service that manages print jobs and allows network devices to send print requests to remote printers. Multiple LPR printer ports can be configured.

IoT Network¶

The IoT Network creates a dedicated Wi-Fi network for IoT devices. Isolated from the primary network, it delivers better compatibility and improved security.

Note: Some models (e.g., GL-MT5000, GL-MT2500/GL-MT2500A) do not have Wi-Fi functionality, thus the IoT Network settings are not available on their web Admin Panel.

In the IoT Network, you can directly view the interface status, VLAN ID, Gateway, and DHCP Range.
