Configuring the Local Network
Quantum Spark 1500, 1600 and 1800 Appliance Series R80.20.40 Locally Managed Administration Guide | 82
The 'Configuration' tab
n
In Bridge Configuration, select the networks you want to be part of the bridge.
n
Enable Spanning Tree Protocol - When Spanning Tree Protocol (STP - IEEE 802.1d) is enabled,
each bridge communicates with its neighboring bridges or switches to discover how they are
interconnected. This information is then used to eliminate loops, while providing optimal routing of
packets. STP also uses this information to provide fault tolerance, by re-computing the topology in the
event that a bridge or a network link fails.
n
Enter a Name for the bridge interface. Note that you can only enter "brN" where N is a number
between 0 and 9. For example, br2.
n
Select the IP address and Subnet mask.
n
Use Hotspot - Select this checkbox to redirect users to the Hotspot portal before allowing access
from this interface. Hotspot configuration is defined in the Device > Hotspot page.
n
DHCP Server
Select one of the options:
l
Enabled - Enter the IP address range and if necessary the IP address exclude range. The
appliance's own IP address is automatically excluded from this range. You can also exclude or
reserve specific IP addresses by defining network objects in the Users & Objects > Network
Objects page. Reserving specific IP addresses requires the MAC address of the device.
l
Relay - Enter the DHCP server IP address.
l
Disabled
The 'Advanced' tab
n
MTU size - Configure the Maximum Transmission Unit size for an interface.
n
Disable auto negotiation - Select this option to configure manually the link speed of the interface.
n
Override default MAC address – This option is for local networks except those on VLANs and
wireless networks. Use this option to override the default MAC address used by the network's
interface, when the device has two separate local networks connected to the same external switch.
Best Practice - This is a rare configuration. Do not select this option unless you are sure you need it.
n
Exclude from DNS proxy – Select this checkbox for any network that you do not want exposed to
internal domains. In guest VAPs (wireless network for guests), this is selected by default.
To configure Advanced IPv6 settings:
1. Configure the Router Advisement fields.
2. Under Prefix Delegation, select the checkbox for Enable prefix delegation and enter the relevant
information.

Logical topology before the change:
[SWITCH] --- VLAN Trunk --- (LAN) [Appliance in Bridge Mode] (WAN) --- VLAN Trunk --- [ROUTER]
