Configuring SSL certificates
If the ISDN gateway has the
Secure management (HTTPS)
or
Encryption
feature key installed, and
you enable the secure web service on the
Network > Services
page, you will be able to access the
web interface of the ISDN gateway using HTTPS. The ISDN gateway has a local certificate and
private key pre-installed and this will be used by default when you access the unit using HTTPS.
However, we recommend that you upload your own certificate and private key to ensure security as all
ISDN gateways have identical default certificates and keys.
To upload your own certificate and key, go to
Network > SSL certificates
, complete the fields and
click
Upload certificate and key
. Note that you must upload a certificate and key simultaneously.
After uploading a new certificate and key, you must restart the ISDN gateway.
If you have uploaded your own certificate and key, you can remove it later if necessary; to do this,
click
Delete custom certificate and key
.
Field
Field description
Usage tips
Local certificate
Subject
The details of the business to which the
certificate has been issued:
C
: the country where the business
is registered
ST
: the state or province where
the business is located
L
: the locality or city where the
business is located
O
: the legal name of the business
OU
: the organizational unit or
department
CN
: the common name for the
certificate, or the domain name
Issuer
The details of the issuer of the certificate.
Where the certificate has been
self-issued, these details will be the
same as for the
Subject
.
Issued
The date on which the certificate was
issued.
Expires
The date on which the certificate will
expire.
Private key
Whether the private key matches the
certificate.
Your web browser uses the SSL
certificate's public key to encrypt
the data that it sends back to the
ISDN gateway. The private key is
used by the ISDN gateway to
decrypt that data. If the
Private key
field shows 'Key matches
certificate' then the data is securely
encrypted in both directions.
