A router is a network device that connects two or more networks
and routes data to the appropriate network. Routers
are commonly used to connect the public Internet
with private local area networks. In this setup,
each computer on the local area network does not
have an “Internet address”. The router's ''external''
Internet IP address is the Internet address for
the whole local area network. The computers on
the local area network have their own “internal”
IP addresses. This allows the computers to communicate
with each other, and allows the router to send
data to the appropriate computer.
The router acts like a switchboard for computers on a local
area network. If you want to connect to a computer
on the LAN, from the Internet, you send data to
the router's IP address. Depending on the setup,
the router connects you to the appropriate computer
on the LAN or drops the connection.
If the Station computer is behind a router and you want remote
monitors to connect across the Internet:
1
Determine
the Station computer’s internal IP address. You
need to know the internal IP when setting up port
forwarding at step 5. To find the IP address:
On Windows® XP and Windows® 2000:
a.
Click the Start button.
b.
Click Run on the start menu.
c.
Type CMD in the Open field.
d.
Click OK.
The
Command Prompt window appears.
e.
Type ipconfig
and press Enter
Your
IP address, subnet mask, and default gateway will
be displayed.
f.
Type Exit
and press Enter
to close the Command Prompt.
On Windows® 95, Windows® 98 and Windows®
ME:
a.
Click the Start button.
b.
Click Run on the start menu.
c.
Type WINIPCFG in the Open field.
d.
Click OK.
The
IP Configuration
window appears.
e.
Select your adapter from the drop-down
menu
Your
IP address, subnet mask and default gateway will
be displayed.
f.
Click OK to close the IP Configuration window.
2
Take
note of the e-Surveiller
Port.
You can see this by opening the e-Surveiller Station,
selecting Settings from the View menu and clicking
the connection tab.
3
Set
any firewall software on your PC to allow incoming
and outgoing connections on the e-Surveiller port.
NOTE: Windows® XP has a built-in firewall that
you must setup to allow incoming and outgoing
connections on the e-Surveiller port. See
firewalls
for more information.
4
If
your router also functions as a firewall, set
the firewall feature to allow incoming and outgoing
connection on the e-Surveiller port. Consult your
router’s documentation on firewall settings.
5
Use
your router’s port forwarding feature to forward
the e-Surveiller port to the Station computer’s
IP address (determined at step 1).
Consult your router’s documentation on setting
up port forwarding.
NOTE:
Port forwarding is also known as port mapping or virtual server.
NOTE:
When setting up port forwarding, if there is an option for UDP or TCP,
Select TCP or Both.
NOTICE: If remote
Monitors are unable to connect to the Station
after setting up port forwarding, you may need
to update your router's firmware. Refer to the
router manufacturer's Web site for information
about possible firmware updates.
6
Configure
your router to allow incoming and outgoing connections
on the e-Surveiller port. Depending on your router, this may be automatically configured after setting
up port forwarding to the Station computer.
7
Configure
your router to allow outgoing connections on IRC
(port 6667), and/or the Gnutella (port 6346) ports.
8
Set
any installed firewall software on your computer
to allow outgoing connections on IRC (port 6667) and/or on Gnutella (port 6346).
NOTE:
The ports for the IRC and Gnutella networks the station connects to may
not be 6667 and 6346. To see what port numbers
the station connects to; check the connections
tab in the station settings window.
NOTE: If the station computer is dynamically
assigned an internal
IP address by the router; you may consider changing
the router DHCP server setting such that the station
computer is assigned a fixed internal IP address. Consult your router’s documentation or router
manufacturer’s support website on setting this
up.
9
If
the computer you want to monitor is behind a router,
perform the following operations:
a.
Configure the router to allow both incoming and outgoing connections
on the e-Surveiller port.
b.
Configure the router to allow outgoing connections on IRC (port 6667)
and/or on Gnutella (port 6346).
c.
Configure any installed software
and hardware firewalls on the monitored computer
to allow (1) both incoming and outgoing connections
on the e-Surveiller port, (2) outgoing
connections on IRC (port 6667) and/or on Gnutella
(port 6346), (3) incoming connections on IDENT (port 113).
d.
Configure the router to forward
the IDENT port (port 113) to the monitored computer,
if you have only one monitored computer behind
the router.
e.
Configure the router to forward
the e-Surveiller port to the monitored computer,
if you have only one monitored computer behind
the router.
