Accessing the Gateway
Direct Access
When the Mac web host computer is not connected to a
computer network, the tekmarNet
® Gateway web pages
are only available directly off the Mac web host computer
connected to the 483. This is called direct access.
To access the tekmarNet ® Gateway web pages, click on the
Safari web browser and enter the following IP address:
http://localhost:3000
The gateway login page will appear. Bookmark this address
to the web browser to allow quick and easy access to the
tekmarNet
® Gateway.
Local Area Network Access
A very common application is to access the tekmarNet ®
Gateway on another computer within the same building.
Both computers will be connected to a Local Area Network
(LAN). Most often the LAN will have a router installed,
although a hub or switch could also be installed. If a
router is installed, follow the instructions in the Router
Configuration section.
To access the tekmarNet ® Gateway web pages from any
computer inside the LAN, find out the Mac web host computer’s
static LAN IP address by following these steps:
STEP 1) On the Mac web host computer, click on the
System Preferences icon.
STEP 2) Click on the Network icon.
STEP 3) Under Built-in Ethernet, the IP address is shown.
Record the LAN IP address for your records.
192.168.0.2
From any computer connected to the LAN, start a web
browser (Internet Explorer, Firefox, or Safari) and enter
this IP address followed by :3000 and press enter. An
example would be:
http://192.168.0.2:3000
The tekmarNet ® Gateway login web page will appear.
Bookmark this address to the web browser to allow quick
and easy access to the tekmarNet
® Gateway while using
a computer inside the LAN.
Internet Access
The tekmarNet ® Gateway can be accessed through the
Internet when using a high speed cable or DSL modem.
The high speed modem may or may not be connected
to a router. If a router is installed, follow the instructions
in the Router Configuration section. If a router is not
installed, follow the instructions in the Mac OS X Firewall
Configuration section.
An Internet Service Provider (ISP) provides an Internet
IP address that can be either static (always the same) or
dynamic (changes on a regular basis). Static IP addresses
are desirable since the address is always the same, making
it easy to locate on the Internet. Static IP addresses usually
require a business account from the ISP. Residential ISP
accounts are often provided a dynamic IP address. In
order to easily access the tekmarNet
® Gateway that has
a dynamic IP address, a free dynamic DNS service is
required. The dynamic DNS service operates by linking
a domain name (example: www.tekmarcontrols.com) to a
dynamic IP address (example: 24.156.244.16). This allows
the IP address to change, while the domain name is always
the same.
Contact your ISP to determine if a static or dynamic IP
address has been provided.
Static IP Address
If the ISP has provided a static IP address, the Mac web
host computer’s IP address can be easily determined by
clicking on the Safari icon to start the web browser and
enter the following address:
http://whatismyip.com
On this web page, the static IP address is shown. Write
down this IP address for your records.
From any computer connected to the Internet, start a web
browser (Internet Explorer, Firefox, or Safari) and enter the
static IP address followed by :3000 and press enter. An
example would be:
http://24.156.244.16:3000
The tekmarNet ® Gateway login web page will appear.

® Gateway while on the
Internet.
