ProSecure Web/Email Security Threat Management (STM) Appliance Reference Manual
3-4 Performing Network and System Management
v1.0, September 2009
Subnet Mask Enter the IP subnet mask. The subnet mask specifies the network number portion of
an IP address. Unless you are implementing subnetting, use 255.255.255.0 as the
subnet mask.
Gateway
Address
Enter the IP address of the gateway through which the STM is accessed.
Primary DNS Specify the IP address for the primary DNS server IP address.
Secondary DNS As an option , specify the IP address for the secondary DNS server IP address.
Interface Speed & Duplex Settings
These sections show for each interface the MAC address, and for each active interface the assigned
speed and duplex setting. The Set Speed/Duplex pull-down menu allows you to select the speed and
duplex setting for each active interface. To set the speed to 1000baseT duplex (“full”), select auto to let
the STM sense the speed automatically.
Note: MGMT stands for management interface.

and duplex mode.
Note: The STM150 does not provide a dedicated management
interface.
