8.1 USB Device Setup

Setup > USB Settings

There are two USB ports on the DSR Unified Services Router. The port supports a 3G
modem where the USB dongle is used as a secondary WAN interface. Additionally,
the port can be used for a USB storage device if USB Disc is type is selected. This
storage can be accessed by LAN devices if appropriate policies are configured.

8.2 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  loaded  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
