Advanced Configuration



4-Port SSL/IPSec VPN Router

to configure the Device IP Address and Subnet Mask

settings.)

Subnet-4

The subnet numbers are created according

to the VLAN numbers. (The multiple subnets can also

be configured on the Setup > Network screen.)

IP Address

Enter an IP address.

Subnet Mask

Select the appropriate subnet mask.

Dynamic IP Range

When the IP Address and Subnet

Mask settings are configured, the range of IP addresses

is displayed. You can change the range of IP addresses

as long as the total number of IP addresses assigned by

DHCP is 253. The greater the number of multiple subnets,

the fewer the number of IP addresses assigned by DHCP.

NOTE:

The Router’s built-in DHCP server can

assign up to 253 IP addresses.

System Management > Diagnostic

The Router has two built-in tools, DNS Name Lookup

and Ping, which are used for troubleshooting network

problems.

The Internet has a service called the Domain Name Service

(DNS), which allows users to enter an easily remembered

host name, such as www.linksys.com, instead of numerical

TCP/IP addresses to access Internet resources. The DNS

Name Lookup tool will return the numerical TCP/IP address

of a host name.
The Ping test bounces a packet off a machine on the

Internet back to the sender. This test shows if the Router

is able to contact the remote host. If users on the LAN

are having problems accessing services on the Internet,

try pinging the DNS server or other machine at the ISP’s

location. If this test is successful, try pinging devices

outside the ISP. This will show if the problem lies with the

ISP’s connection.

Diagnostic

DNS Name Lookup/Ping

Select which tool you want

to use, DNS Name Lookup or Ping. Then proceed to the

appropriate instructions.

DNS Name Lookup

Before using this tool, make sure the IP address of the DNS

server is entered on the Setup > Network screen; otherwise,

this tool will not work.

System Management > Diagnostic > DNS Name Lookup

Look up the name

Enter the host name, and click Go.

(Do not add the prefix http:// or else you will get an error

message.) The Router will then query the DNS server and

display the result at the bottom of the screen.

Ping

Before using this tool make sure you know the device or

host’s IP address. If you do not know it, use the Router’s

DNS Name Lookup tool to find the IP address.
