2. Getting Started

This chapter explains how to access the EtherDevice Router for the first time. There are three ways to access
the switch: (1) serial console, (2) Telnet console , or (3 ) web browser. The serial console connection method,
which requires using a short serial cable to connect the EtherDevice Router to a PC’s COM port, can be used if
you do not know the EtherDevice Router’s IP address. The Telnet console and web browser connection methods
can be used to access the EtherDevice Router over an Ethernet LAN, or over the Internet. A web browser can
be used to perform all monitoring and administration functions, but the serial console and Telnet console only
provide basic functions.

The following topics are covered in this chapter:

Using Telnet to Access the EtherDevice Router’s
Console

You may use Telnet to access the EtherDevice Router’s console utility over a network. To access the EDR’s
functions over the network (by either Telnet or a web browser) from a PC host that is connected to the same
LAN as the EtherDevice Router, you need to make sure that the PC host and the EtherDevice Router are on the
same logical subnet. To do this, check your PC host’s IP address and subnet mask. By default, the EtherDevice
Router’s LAN IP address is 192.168.127.254 and the EtherDevice Router’s subnet mask is 255.255.255.0 (for
a Class C subnet). If you do not change these values, and your PC host’s subnet mask is 255.255.0.0, then its
IP address must have the form 192.168.xxx.xxx. On the other hand, if yo ur PC host’s subne t ma sk is

255.255.255.0, then its IP address must have the form, 192.168 .127 .xx x .

NOTE

To use the

EtherDevice Router’

s management and monitoring functions from a PC host connected to the same

LAN as the

EtherDevice Router, you must make sure that the PC host and the EtherDevice Router are

connected to the same logical subnet.

NOTE

Before accessing the console utility via Telnet, first connect the

EtherDevice Router’

s RJ45 Ethernet LAN ports

to your Ethernet LAN, or

directly to your PC’s Ethernet card (NIC). You can use either a straight-

through or

cross-over Ethernet cable.

NOTE

The

EtherDevice Router’s default LAN IP address is 192.168.127.254.

on page 2-3.

Using a Web Browser to Configure the
EtherDevice Router

The EtherDevice Router’s web browser interface provides a convenient way to modify the switch’s configuration
and access the built-in monitoring and network administration functions. The recommended web browser is
Microsoft Internet Explorer 6.0 with JVM (Java Virtua l Mac hine) installe d.

NOTE

To use the

EtherDevice Router’

s management and monitoring functions from a PC host connected to the same

LAN as the

EtherDevice Router, you must make sure that the PC host and the EtherDevice Router are

connected to the same logical subnet.

NOTE

Before accessing th e

EtherDevice Router’s web browser, first connect the EtherDevice Router’

s RJ45 Eth ernet

LAN ports to your

Ethernet LAN, or directly to your PC’s Ethernet card (NIC). You can use either a

straight

-through or cross-over Etherne t c able .

NOTE

The

EtherDevice Router’s default LAN IP address is 192.168.127.254.

3. Features and Functions

In this chapter, we explain how to access the EtherDevice Router’s configuration options, perform monitoring,
and use administration functions. There are thr ee ways to acces s thes e func tions: (1) RS-232 console, (2)
Telnet console, and (3) web browser.

The web browser is the most u ser-friendly way to configure the EtherDevice Router, since you can both monitor
the EtherDevice Router and use administration functions from the web browser. An RS-232 or Telnet console
connection only provides basic functions. In this chapter, we use the web browser to introduce the EtherDevice
Router’s configuration and monitoring f unc ti o ns .

Accessible IP

The EtherDevice Router uses an IP address-based filtering method to control access to EtherDevice Router
units.

Accessible IP Settings allows you to add or remove “Legal” remote host IP addresses to prevent unauthorized
access. Access to the EtherDevice Router is controlled by IP address. If a host’s IP address is in the accessible
IP table, then the host will have access to the EtherDevice Router. You can allow one of the following cases by
setting this parameter:

• Only one host with the specified IP address can access this device.

E.g., enter “192.168.1.1/255.255.255.255” to allow access to just the IP address 192.168.1.1.

• Any host on a specific subnetwork can access this device.

E.g., enter “192.168.1.0/255.255.255.0” to allow access to all IPs on the subnet defined by this IP
address/subnet mask combination.

• Any host can access the EtherDevice Router. (Disable this function by deselecting the Enable the accessible

IP list option.)

• Any LAN can access the EtherDevice Router. (Disable this function by desele c ting the LAN option to not

allow any IP at the LAN site to access this device.)
E.g., If the LAN IP Address is set to 192.168.127.254/255.255.255.0, then IP ad dresses 192.168.127.1 /24
to 192.168.127.253/24 can access the EtherDevice Router.

or time.nist.gov).

None

2nd Time Se r ver
IP/Name

The EtherDevice Router

will try to locate the 2nd NTP Server if

the 1st NTP Server fails to connect.

SettingCheck

SettingCheck is a safety function for industrial users using a secure router. It provides a double confirmation
mechanism for when a remote user changes the security policies, s uc h as Firewall filter, NAT, and
Accessible IP list. When a remote user changes these security polices, SettingC he ck provides a means of

blocking the connection from the remote us er to the Firewall/VPN device. The only way to correct a wrong
setting is to get help from the local operator, or go to the local site and connect to the device through the
console port, which could take quite a bit of time and money. Enabling the SettingCheck function will execute
these new policy changes temporarily until doubly confirmed by the user. If the user does not click the confirm
button, the EtherDevice Router will revert to the previous setting.

Firewall Policy

Enables or Disables the SettingCheck function when the Firewall p olicies change.

NAT Policy

Enables or Disables the SettingCheck function when the NAT po lic ie s change.

Accessible IP List

Enables or Disables the SettingCheck func tio n when the Acces s ible IP List changes.

The timer waits this amount of time to double confirm when the

user changes the policies

180 (sec.)

For example, if the remote user (IP: 10.10.10. 10) connects to the EtherDevice Router and changes the
accessible IP address to 10.10.10.12, or deselects the Enable checkbox accidently after the remote user clicks
the Activate button, connection to the EtherDevice Router will be lost because the IP address is not in the
EtherDevice Router’s Accessible IP list.

If the user enables the SettingCheck function with the Accessible IP list and the confirmer Timer is set to 15
seconds, then when the user clicks the Activate button on the accessible IP list page, the EtherDevice Router
will execute the configuration change and the web browser will try to jump to the SettingCheck Confirmed page
automatically. Because the new IP list does not include the Remote user’s IP address, the remote us er can not
connect to the SettingCheck Confirmed page. After 15 seconds, the EtherDevice Router will roll back to the
original Accessible IP List setting, allowing the remote user to reconnect to the EtherDevice Router and check
what’s wrong with the previous setting.

If the new configuration does not block the connection from the remote user to the EtherDevice Router, the
user will see the SettingCheck Confirmed page, shown in the following figure. Click Confirm to save the
configuration updates.
