8.4 Authentication Certificates
Advanced > Certificates
This gateway uses digital certificates for IPsec VPN authentication as well as SSL
validation (for HTTPS and SSL VPN authentication). You can obtain a digital
certificate from a well-known Certificate Authority (CA) such as VeriSign, or
generate and sign your own certificate using functionality available on this gateway.
The gateway comes with a self-signed certificate, and this can be replaced by one
signed by a CA as per your networking requirements. A CA certificate provides
strong assurance of the server’s identity and is a requirement for most corporate
network VPN solutions.
The certificates menu allows you to view a list of certificates (both from a CA and
self-signed) currently load ed on the gateway. The following certificate data is
displayed in the list of Trusted (CA) certificates:
CA Identity (Subject Name): The certificate is issued to this person or organization
Issuer Name: This is the CA name that issued this certificate
Expiry Time: The date after which this Trusted certificate becomes invalid
A self certificate is a certificate issued by a CA identifying your device (or self -
signed if you don’t want the identity protection of a CA).
The Active Self Certificate

table lists the self certificates currently loaded on the gateway. The following
information is displayed for each uploaded self certificate:
Name: The name you use to identify this certificate, it is not displayed to IPsec
VPN peers or SSL users.
Subject Name: This is the name that will be displayed as the owner of this
certificate. This should be your official registered or company name, as IPsec or
SSL VPN peers are shown this field.
Serial Number: The serial number is maintained by the CA and used to identify
this signed certificate.
Issuer Name: This is the CA name that issued (signed) this certificate
Expiry Time: The date after which this signed certificate becomes invalid
you
should renew the certificate before it expires.
To request a self certificate to b e signed by a CA, you can generate a Certificate
Signing Request from the gateway by entering identification parameters and pass ing it
along to the CA for signing.
Once signed, the CA’s Trusted Certificate and signed
certificate from the CA are uploaded to activate the self-certificate validating the
identity of this gateway. The self certificate is then used in IPsec and SSL
connections with peers to validate the gateway’s authenticity.

Advanced Switch Configuration
The DSR allows you to adjust the power consumption of the hardware based on your
actual usage.
The two “green” options available for your LAN switch are
Power
Saving by Link Status and Length Detection
State. With “Power Saving by Link
Status” option enabled, the total power
consumption by the LAN switch is dependent
function of on the number of connected ports. The overall current draw when a single
port is connected is less than when all the ports are
connected. With “Length
Detection State” option enabled, the overall current supplied to a LAN port is reduced
when a smaller cable length is connected on a LAN port.
Jumbo Frames support can be configured as an advanced switch configuration. Jumbo
frames are Ethernet frames with more than 1500 bytes of payload. When this option is
enabled, the LAN devices can exchange information at Jumbo frames rate.

Configuration Access Control
The primary means to configure this gateway via the browser-independent GUI. The
GUI can be accessed from LAN node by using the gateway’s LAN IP address and
HTTP, or from the WAN by using the gateway’s WAN IP address and HTTPS (HTTP
over SSL).
Administrator
and Guest users are permitted to login to the router’s management
interface. The user type is set in the
Advanced > Users > Users
page. The Admin or
Gues t user can be configured to access the router GUI from the LAN or the Internet
(WAN) by enabling the corresponding Login Policy.

Both HTTPS and telnet access can be restricted to a subset of IP addresses. The
router administrator can define a known PC, single IP address or range of IP
addresses that are allowed to access the GUI with HTTPS. The opened port for SSL
traffic can be changed from the default of 443 at the same time as defining the
allowed remote management IP address range.
