other devices on your wireless network. We recommend you use a name that is meaningful to you so you
can identify the Gateway easily. The Gateway name is case sensitive and can contain from 8 to 20
alphanumeric characters, but no spaces or special characters.
Current Password Enter the current case-sensitive password. For security purposes, every typed character appears as a dot
(y). The default password is not shown for security purposes. The password is case sensitive and can
contain from 8 to 32 characters, but no spaces or special characters.
New Password Enter the new case-sensitive password you want to use to protect your network. The password can contain
from 8 to 32 alphanumeric characters, but no spaces or special characters. Spaces count as password
characters. For security purposes, every typed character appears as a dot (y).

Option Description
Enter WiFi Network Name Enter a name for your wireless network (typically, the SSID). The Wi-Fi name will make it more obvious for
other devices to know which network they are connecting to.
Encryption Method To prevent other computers in the area from using your Internet connection, secure your wireless network by
selecting an encryption method from this drop-down list. There are several selections available, including the
following. (Risky appears next to selections that provide little or no protection).
• Open = wireless transmissions are not protected.
• WEP = basic encryption and therefore least secure (i.e., it can be easily cracked, but is compatible with a
wide range of devices including older hardware). WEP 64- and 128-bit selections are provided.
• WPA-PSK = designed for home and small-office networks. Each wireless network device encrypts the
network traffic using a 256-bit key. Select this option if your wireless adapters support Wi-Fi Protected
Access Pre-shared Key (WPA-PSK) mode.
• WPA2 = second generation of WPA that adds CCMP encryption with mathematically proven security.
Select this option if your wireless adapters support WPA2.
Enter Network Password If you select one of the WEP or WPA encryption settings, enter the case-sensitive password used for
encryption and decryption. For security, each typed password character is masked as a dot (λ). If you
specify a hexadecimal password, use the letters A to F and numbers 0 to 9.
• WEP 64 requires a 5 ASCII character or 10 hexadecimal character password.
• WEP 128: requires a 13 ASCII character or 16 hexadecimal character password.
• WPA-PSK (TKIP) requires an 8-to-63 ASCII character or a 64 hexadecimal character password.
• WPA-PSK (AES) requires an 8-to-63 ASCII character or a 64 hexadecimal character password.
• WPA2-PSK (TKIP) requires an 8-to-63 ASCII character password.

When port triggering is enabled, the Gateway monitors outbound traffic. If the Gateway detects traffic
on the specified outbound port, it remembers the IP address of the computer that sent the data, triggers
the incoming port, and then forwards the incoming traffic to the triggering computer.
To use port triggering, you specify which service type and port number you want to track, along with
other related parameters. This allows the Gateway to pass the special applications to the appropriate
ports you specified.

Update Interval Specify how often, in seconds, the Gateway sends routing-update messages.
Default Metric Enter a number by which the metric value for the path increases when the Gateway receives a routing
update that includes changes to an entry. Choices are 1 – 15. Default is 1.
Authentication Type Select the authentication mechanism used, if any. Choices are:
• No Authentication = no authentication is used. If you keep this default setting, the Authentication
Key & ID fields are gray and unavailable.
• Simple Password = an authentication method where a clear text password is sent to participating
neighbors on the network. This selection sends the authenticating password over the network,
possible making it available to individuals who can access packets off the network. Do not use this
option as part of your security strategy, Rather, use it to avoid accidental changes to the routing
infrastructure. If you select this setting, the first field in the Authentication Key & ID option becomes
available for entering the password.
• md5 = an authentication method that works much like Simple Password authentication, except that
MD5 does not send the key over the network. Instead, a router uses the MD5 algorithm to produce
a message digest of the key (also called a hash). The router sends the message digest instead of
the key itself, which ensures that no one can eavesdrop on the network and learn keys during
transmission. If you select this setting, the first field in the Authentication Key & ID option becomes
available for entering the key and the second field becomes available for entering the ID.
Authentication Key & ID Specify the appropriate information based on the Authentication Type selected:
• No Authentication = no entry required.
• Simple Password = in the first field, enter the clear-text password to be used for authentication.
The second field requires no entry, and is gray and unavailable.
• md5 = in the first field, enter the MD5-hash password. In the second field, enter the Key Identifier
that identifies the key used to create the authentication data for this message.
Neighbor IP Enter the IP address of the Gateway’s RIP neighbor router.

you can configure the computer for unrestricted two-way Internet access by defining it as a Virtual DMZ
host. A DMZ allows a single computer on your LAN to expose its ports to the Internet. When doing this,
the exposed computer is no longer “behind” the firewall. Therefore, placing a computer in the DMZ
should be considered temporary because the firewall is no longer able to provide any security to it.

QoS Page
Path: Advanced > QoS
The QoS page lets you configure the Gateway to deliver better resource reservation control. Wireless
networks offer an equal opportunity for all devices to transmit data from any type of application.
Although this is acceptable for most applications, multimedia audio and video applications are
particularly sensitive to the delay and throughput variations that result from this “equal opportunity”
wireless access method. For multimedia applications to run well over a wireless network, a Quality of
Service (QoS) mechanism is required to prioritize traffic types and provide an “enhanced opportunity”
wireless access method.
The QoS page lets you enable or disable QoS settings. After making your selections, click the SAVE
button to apply them. You can change QoS settings without having to reboot the Gateway.

Device Discovery Page
Path: Advanced > Device Discovery
Universal Plug and Play (UPnP) is an architecture that allows for dynamic connectivity between devices
on a network. The goal of UPnP is to support zero-configuration, "invisible" networking of devices
including intelligent appliances, PCs, printers and other smart devices using standard protocols.
Using UPnP, devices can add themselves to a network dynamically, without requiring user intervention
or configuration. A UPnP-enabled device can obtain an IP address, advertise its capabilities, learn
about other connected UPnP devices, and then communicate directly with those devices. The same
device can end its connection cleanly when it wishes to leave the UPnP community.
Using the Device Discovery page, the Gateway can discover all UPnP-enabled devices on the network.
After making your selections, click the SAVE button to apply them.
Figure 53. Device Discovery Page
88
SMCD3GNV4 and SMCD3GNV4E Wireless EMTA Gateway Administrator Manual
Table 27. Device Discovery Page Options
Option Description
Enable UPnP Determines whether the Gateway’s UPnP capabilities are enabled or disabled. Choices are:
• Enabled = enables the Gateway’s UPnP capabilities.
• Disabled = disables the Gateway’s UPnP capabilities.
Advertisement Period Specify how often, in seconds, the Gateway broadcasts its UPnP information. This value can
range from 1 to 2147483648 seconds. Short durations ensure that control points have current
device status at the expense of additional network traffic. Long durations can compromise the
freshness of the device status, but can significantly reduce network traffic.
Time To Live Configure the number of hops (steps) for the advertisement time to live. The time to live for the
advertisement is measured in hops for each UPnP packet sent. The time to live hop count is the
number of steps a broadcast packet is allowed to propagate for each UPnP advertisement
before it disappears. The number of hops can range from 1 to 255. The default setting should be
fine for most home networks. If some of your devices are not being updated or reached
correctly, you can increase this value slightly.

VPN Global Page
Path: Advanced > VPN > Global
A Virtual Private Network (VPN) is a technology designed to increase the security of information
transferred over the Internet. A VPN creates a private encrypted tunnel from the user's computer,
through the local wireless network, through the Internet, all the way to the corporate servers and
database.
The Gateway supports the Internet Protocol Security (IPSec) to secure IP traffic. IPSec builds “virtual
tunnels” between a local and remote subnet for secure communication between two networks. This
connection is commonly known as a Virtual Private Network (VPN).
Alternatively, tunneling protocols such as Point-to-Point Tunneling Protocol (PPTP) and Layer Two
Tunneling Protocol (L2TP) can be used to achieve a secure connection (such as to a corporate LAN)
over the Internet. These tunneling protocols can optionally be secured themselves using IPSec.
Using the Global settings page, you can enable or disable the Gateway’s VPN settings.

#Key Management
IKE Negotiation Mode Select the IKE operating mode. Choices are:
• Main = creates an encrypted channel before exchanging the identities.
• Aggressive = quicker than Main Mode, exchanges endpoint IDs in “clear text”, while performing
Diffie-Hellman (DH) exchange and establishing the secure channel. Aggressive Mode is less secure than
Main Mode.
IKE DH Group Select the DH group that will produce the secret shared value. The strength of the technique is that it allows
participants to create the secret value over an unsecured medium without passing the secret value through the
wire. You can select from three DH groups. The size of the prime modulus used in each group's calculation
differs as follows:
• Group 2 = D-H Group 2 algorithm is used for the Diffie-Hellman Key Exchange. DH Group 2 uses a 1024-bit
encryption.
• Group 5 = D-H Group 5 algorithm is used for the Diffie-Hellman Key Exchange. DH Group 5 uses a 1536-bit
encryption.
• Group 6 = D-H Group 6 algorithm is used for the Diffie-Hellman Key Exchange. DH Group 6 offers the
highest key size and the highest level of security.
IKE Pre-shared Key Enter a “pass code”. The pass code must be the same at both the local and the remote side. Both ends of the
tunnel must use the same key; otherwise, the VPN tunnel cannot be established.
IKE Hash Checks that the data has not changed in transmission. Both ends of the tunnel must use the same setting;
otherwise, the VPN tunnel cannot be established. Choices are:
• md5 = faster than SHA, but less secure.
• SHA1 = a one-way hashing algorithm that produces a 160-bit digest. SHA is more secure than MD5
IKE Encryption Encryption algorithm used during the Authentication phase. Choices are
• 3des = triple DES is a symmetric strong encryption algorithm that is compliant with the OpenPGP standard.
It is the application of DES standard, where three keys are used in succession to provide additional
security.
• aes = Advanced Encryption Standard offers the highest standard of security. The effective key lengths that
can be used with AES are 128, 192, and 256 bits. The higher the bit rate, the stronger the encryption but the
trade-off is lower throughput. More secure than 3DES.
Both ends of the tunnel must use the same setting; otherwise, the VPN tunnel cannot be established.
#IP Sec
94
SMCD3GNV4 and SMCD3GNV4E Wireless EMTA Gateway Administrator Manual
Option Description
IPSec Encryption Select the authentication algorithm used to encrypt packet data. Choices are
• 3des = more secure method than DES, but with lower throughput.
• aes = more secure than 3DES. The higher the bit rate, the stronger the encryption but the trade-off is lower
throughput.
• null = no authentication used..
Both ends of the tunnel must use the same setting; otherwise, the VPN tunnel cannot be established. This field
is gray and unavailable if AH is selected for IPSec operation.
IPSec Authentication Authentication method used when ESP is selected for IPSec Operation. Both ends of the tunnel must use the
same setting; otherwise, the VPN tunnel cannot be established. Choices are:
• md5 = a one-way hashing algorithm that produces a 128-bit digest. (default)
• sha = a one-way hashing algorithm that produces a 160-bit digest. SHA is more secure than MD5.
IPSec SA Life Enter the number of seconds for the IPSec lifetime. This is the period of time that can pass before establishing
a new IPSec security association (SA) with the remote endpoint.
Perfect Forward Secrecy Ensures that a session key derived from a set of long-term public and private keys will not be compromised if
one of the (long-term private keys is compromised in the future. Both sides of the VPN must be able to support
Perfect Forward Secrecy in order for it to work.
• enable = ensures the same key will not be generated again, forcing a new D-H key exchange.
• disable = feature is disabled.
IPSec DH Group Select the D-H group used during the VPN negotiation stage. Choices are:
• group 2 = provides basic security and good performance.
• group 5 = like group 2. Actual initialization and rekey speed depend on a number of factors.
• group 6 = offers the fastest performance. If performance times are a problem for your network, change to a
lower DH group.

2. Measure the gap between holes with a ruler. Dimensionally confirm the template by measuring each
value for accuracy before drilling holes.
3. Use a center punch to mark the center of the holes.
4. Locate the marks on the wall for the mounting holes.
5. Drill holes to a depth and diameter appropriate for the size and type of hardware you have selected.
6. If necessary, install an anchor in each hole. Use M3.5 x 40 mm screws with a flat underside and
maximum screw head diameter of 6.5 mm (0.25 inches) to mount the Gateway.
7. Using a screwdriver, turn each screw until the head protrudes from the wall. The figure below is an
example for mounting Gateway on a concrete surface. Leave at least 2.5 mm (0.10 inches) between
the wall and the underside of the screw head. The maximum distance from the wall to the top of the
screw head is 5.0 mm (0.20 inches).
8. Place the Gateway so the keyholes are above the mounting screws.
9. Slide the Gateway down so it stops against the top of the keyhole opening.
10. Reconnect the coaxial cable and Ethernet cables. Reconnect the power cord to the Gateway and the
electrical outlet.
