The 'Advanced' tab
The options that are shown vary based on interface type and status. Configure the options that
are applicable:
n
Description - Enter an optional description. The description is shown in the local network
table next to the name.
n
MTU size - Configure the Maximum Transmission Unit size for an interface. Note that in
the Quantum Spark Appliance, the value is global for all physical LAN and DMZ ports.
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 of
the network's interface:
l
When the device has two separate local networks connected to the same external
switch.
l
If the ISP is searching for the gateway MAC address to accept the connection. If
you upgrade your new gateway, the ISP may block it because the new gateway
has a different MAC address. In this case, you can override the gateway MAC
address with the old one.
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.
The 'Access Policy' tab (only for DMZ)
These options create automatic rules that are shown in the Access Policy > Firewall Policy
page.
n
Allow access from this network to local networks
n
Log traffic from this network to local networks

Note - Bridge interface supports only two subordinate interfaces.
If you add three or more subordinate interface, then the appliance drops the traffic
through this Bridge interface with the message "IP routing failed (bridge routing
failure)".
To create/edit a bridge, configure the fields in the tabs:
