On rare occasions, it may be necessary to change the Ethernet hardware or MAC Address of your UTM
Firewall appliance. The MAC address is a globally unique address and is specific to a single UTM Firewall
appliance. It is set by the manufacturer and should not normally be changed. However, you may need to
change it if your ISP has configured your ADSL or cable modem to only communicate with a device with
a known MAC address.
Enter a MAC address in the MAC field. The address can be an Ethernet MAC address of the form
AA:BB:CC:DD:EE:FF
, where each of the components is a hexadecimal digit.
Note:
This setting cannot be changed for the LAN port or Port A.

[Optional] If an Ethernet port is experiencing difficulties auto-negotiating with another device, you can
manually set Ethernet speed and duplex from the Ethernet Speed list. Available options are:
• Default Auto Negotiation
• 100 Base Tx - Auto Duplex
• 100 Base Tx - Full Duplex
• 100 Base Tx - Half Duplex
• 10 BaseT - Auto Duplex
• 10 BaseT - Full Duplex
• 10 BaseT - Half Duplex
• 100 Base T4

Specify the MTU (Maximum Transmission Unit) for the interface in the MTU field. This setting should
normally be left at 1500. The value can be an integer equal to or greater than 1.
Note:
This setting only effects the Ethernet interface, and does not change the MTU for ADSL PPPoE interfaces.

[Optional. Models SG560, SG560U, SG565, or SG580 only.] To enable the VLANs of the switch, select the
Enable Port-based VLANs checkbox. When enabled, each port in the switch can be assigned to
different VLANs. The primary reason for using port-based VLANs is to isolate each port in the switch. This
allows you to connect different networks to each port, and to enforce firewall policies between ports. After
enabling port-based VLANs, you need to create VLANs on the Connections page, modify the VLANs, and
assign ports to each VLAN on the VLAN Configuration tab. Any ports that are left unassigned will use the
default VLAN as described below. Port 1 will always use the default VLAN. You can also use the Quick
Setup Wizard to automatically create separate VLANs for each port. After disabling port-based VLANs, any
VLANs you have created will remain as tagged VLANs. You should delete them if they are unneeded.
