Task
Step 1
Within Manager, right click the Logical
LAN entity and create a new Logical
LAN.
Step2
Logical LAN values
• Name = LLAN
• IP Address = 217.37.69.116
• IP Mask = 255.255.255.248
• Gateway IP Address =
<217.37.69.118>
• Gateway MAC Address =
<MAC address of the ADSL router>
* See Note below*
• Firewall Profile = <un-configured>
Step 3
Within Manager, right click the IP
Route entity and create a new IP
Route. Add a default route for Internet
access pointing to the Logical LAN
interface.
• IP Address = <un-configured>
• IP Mask = <un-configured>
• Gateway = <un-configured>
• Destination = LLAN
Step 4
Check the configuration. It should be
possible to perform the following.
• PING the ADSL router
• Browse the Internet
* Note: One method of obtaining the MAC address of the default gateway is to plug
IP Office (R3.0) Virtual Private Networking

your PC directly into the DSL Router, use ipconfig /renew to obtain the Default
Gateway IP Adress. Ping this address and then obtain the MAC address of the
ADSL router by checking your PC's arp cache with the arp -a command.

Description
See page 33.
The logical interface is in effect a secondary LAN
and is normally used on single LAN IP Office
system, to connect to ADSL routers for example.
Name – A name for the Logical LAN
The Gateway IP Address and Gateway MAC
Address will be that of the ADSL. * See Note below:
NAT is enabled by default on the logical interface
and cannot be disabled.
IP Office facilitates the locally originated system to
tunneling traffic through an attached NAT enabled
interface. NAT is applied to traffic that is not
tunneled using the Logical LAN interface address.
See page 33.
The Logical LAN interface is a special case and
does not require the use of the Gateway parameter
for the IP route configuration.
It will not be possible to PING the Internal LAN
from the Internet.
Do not proceed until all tests are successful.
