Gateway and SMTP
The Gateway is used for setting the BLACKBOX Portable’s default Gate-
way IP address. This address is used when the BLACKBOX Portable needs
to send data to IP addresses outside its LAN2 and Internal Link network
range. Typically this is set to the internal router.
The SMTP Server is used for setting an IP Address for Email Server to be
used for sending notification emails.
Ports Setup: This is a legacy option for remote access. Port Setup enables
changing the standard configuration of internet port numbers for standard
communication protocols (Emails, File Transfer, & Web browsing). This
might be used in networks where standard port numbers are forbidden or re-
served by firewalls or in case one wishes to reserve the standard port number
for a legacy modem/router that does not support port forwarding. (Notice
that most external modems/routers on the market today do support port for-
warding). It is suggested to leave the port numbers in their default setup so
that it will be straight forward for web browsers or FTP clients to access the
device via LAN/Internet.
 The SMTP Port is used for setting port number of mail transfer.
 The HTTP Port is used for setting port number of Web browsing.
