Changing the LAN interface configuration
In some cases it is necessary to disable DHCP or to change the default LAN IP
address and subnet mask. For example, you may want to add the Q2200 router to an
existing LAN via one of its Ethernet LAN ports, or you may need to use static
(fixed) IP addresses in the LAN.
a
Go to the
Configure > Interfaces > Ethernet Ports 1-4
page. From the iplan
Controls
list, select
Edit IP
.
If you already have a DHCP server
or you want to use static LAN IP
addresses on the LAN, clear the DHCP Server Enable check box.
–– or –
If you want the Q2200 router to be the DHCP server in the LAN but are
modifying the router’s LAN IP address,
c
hange the default IP address
and subnet mask to match the new subnet and click
OK
. The IP address
ranges will automatically update to reflect the new LAN subnet.
b
At this point, the computer you connected to the router will no longer be
able to communicate with the router, but do not reboot or power down the
router or you will lose all of your changes.
c
Configure the computer to communicate with the router under one of the
following scenarios.
If you disabled DHCP in the router because the LAN has an existing
DHCP server, you can now connect another LAN port on the router to
the existing LAN. Restart the computer to make it obtain a new IP
address on the new subnet.
– or –
If you do not have a DHCP server for the new subnet, configure the
computer with a static address on the new LAN subnet. Restart the
computer to make the changes take effect.
– or –
If the router is the DHCP server, restart the computer to make it obtain a
new IP address on the new subnet.
d
The computer should now be able to communicate with the router. Log in
using the new password, and continue the setup process.
T1 WAN interface configuration
Several settings are required to make the T1 connection to the WAN operational.
a
Go to the
Configure > Interfaces > T1 Port 1
page. From the Configuration
list, select
Edit
, and enter the IP address and subnet mask as you did in
Also verify that the correct protocol, PPP or Frame Relay, is configured for
your T1 service.
b
Check the settings in the other sections of the page to ensure they match
the information supplied by your service provider. If you are unsure about
anything on the page, click Help for further information or contact your
system administrator.
