information.
User Remote Access (from the Internet)
Users can access Intranet resources on the private LAN by
successfully logging into the Internet Firewall from the
Internet. Logging in requires a valid user name and
password, which are transmitted to the Internet Firewall by
the remote user, using a Web browser, through an
MD5-based encrypted security mechanism. Once logged
in, remote users are able to access all IP resources on the
LAN. See
“Setting up the DHCP Server”
on
page 60
for
more information.
Automatic IP Address Sharing and Configuration
The Internet Firewall provides sharing of a single public IP
address through
Network Address Translation
(
NAT
). It also
provides simplified IP address administration using the
Dynamic Host Configuration Protocol
(
DHCP
).
NAT automatically translates multiple IP addresses on the
small business LAN to one public address that is sent out to
the Internet. It enables the Internet Firewall to be used with
broadband modems such as the OfficeConnect Cable
Modem, and with low cost Internet accounts where only
one IP address is provided by the ISP. See
“Network
Addressing Mode”
on
page 50
for more information.
The DHCP server automatically assigns all PCs on the LAN
with the correct IP information. The DHCP client allows the
Internet Firewall to acquire the correct IP settings from the
ISP. See
“Setting up the DHCP Server”
on
page 60
for more
information.
