2.1.2 Subnet Mask
The subnet mask is used to identify sub networks from a given IP address.
This allows the possibility to break down a single network into a number of smaller networks.
Possible values for Subnet Mask are
Ask your network administrator for the subnet mask of the network to which you intend to add the ipGateway.
2.1.3 Gateway
The Gateway is the IP Address of the Default Gateway on the local network. This is generally the IP Address of
a router on the network that provides access to the public network (i.e. the internet).
2.1.4 SMTP Server Address
The SMTP Server Address is the IP address of the email server on the local network (i.e. the server which is
hosting Microsoft Exchange). Ask your network administrator for this information.
2.1.5 TCP Port Number
The ipGateway is configured to use port 80 to receive data. This information is presented purely for information
purposes and cannot be changed.
2.1.6 Email Address
This is the email address that will be used in the “From” field of any email sent from the ipGateway.
2.1.7 SMTP Username
A SMTP (Simple Mail Transfer Protocol) server is the server required to send email.
The SMTP username is used by the SMTP server to check that the user is a legitimate user on the mail server.
2.1.8 SMTP Password
An SMTP password is used by the SMTP server when it is configured to use SMTP Authentication to send
email.
The process of SMTP Authentication requires the user to be a valid user on the SMTP server. Each user on the
SMTP server will have a password associated with it. The device wishing to send the email, in this case
ipGateway, must pass this username along with the valid password to the SMTP server.
In general the SMTP server will use authentication if the “To” address is outside of the SMTP server domain, i.e.
an external email address.
If the username or password is invalid, no email will be sent by the SMTP server.
