5.9.4 ZIPB Advanced configuration

Note: You must ensure that ZIPB is in a disabled state before you carry out any

configuration changes. Once you have changed the configuration and clicked on OK,

you can enable ZIPB and changes will be reflected in the configuration. Any changes

made to the configuration while ZIPB is enabled will be ignored.

You can configure the following advanced settings:

LAN interface:

Select the LAN interface that ZIPB will run on. Usually

Ethernet-0

.

WAN interface:

Select the WAN interface that ZIPB will run on. Usually

ppp-0.

LAN IP address spoof method:

Set the LAN IP address spoof method. Once a public IP

address is assigned to the LAN PC, an IP address on the

same subnet as the public IP address must be created and

assigned to the device’s LAN interface. This option

configures how the LAN interface IP address is created.

Click on the

LAN IP address spoof method

drop down list

and select one of the following:

Top of subnet:

Selects the highest available address in the subnet

Bottom of subnet:

Selects the lowest available address in the subnet

Increment:

Increments the assigned IP address by 1

Manual:

Uses the IP address specified in the Manual LAN IP address

field.

Use PPP server address:

Uses the address of your PPP server.

Manual LAN IP address:

Set the manual LAN IP address only if you selected Manual

as your LAN IP address spoof method.

LAN subnet mask selection method:

Set the LAN subnet mask selection method. You can

select one of the following methods:

Natural:

Uses the subnet mask of the assigned IP address

Manual:

Uses the netmask specified in the Manual LAN subnet mask

field

Manual LAN subnet mask

:

Set the manual LAN subnet mask only if you selected

Manual

as your

.

LAN DHCP server lease time

:

Set the LAN DHCP server lease time duration, in seconds,

of DHCP leases on the LAN.

LAN PC power down time:

set the LAN PC power down time duration, in seconds, of

down time before ZIPB assumes that the LAN PC has been

turned off and that the user no longer needs access to the

Internet.

Once you have configured ZIPB, click on the

OK

button.

Note: that the configuration changes will not take effect until ZIPB is set to enabled. Click

on the Enable button at the top of the page.

5.9.5 Limitations of ZIPB

If Dynamic ZIPB is enabled, traffic originating from your CopperJet, such as pings or one-

click update requests bound for the Internet, will not receive a reply. This is because traffic

will appear to come from the public IP address and will therefore always be routed back to

the PC that is currently sharing the public IP address. Only responses to traffic originating

from a PC on the LAN can be routed back.

5.11 DHCP Server

DHCP allows you to dynamically assign IP address to the computers connected to the

Ethernet of the CopperJet. The CopperJet allows multiple DHCP Servers for multiple IP

subnets. Usually, you would only require 1 DHCP Server.

To enable the DHCP Server, go to the

Configuration

menu and select
