Chapter 5: Configuring the CopperJet
Click on the Enable button to enable ZIPB. Click on the Choose which computer will use the
public IP address drop-down list and select a LAN PC. The public WAN IP address will be
shared with this PC, and the PC will no longer need to go through NAT. Click Apply.
Find below an example on how to get ZIPB to work.
Example:
• Make sure that you have a working routed WAN connection configured.
• Make sure that the DHCP server of the CopperJet is enabled and that your network
card of your pc is on obtain IP address automatically.
• When the DHCP server is enabled and the network card of the pc is set to obtain IP
address automatically, the pc name is available in the list.
• Configured ZIPB as follows:
- Select “ethernet-0” as LAN interface
- Select “rfc1483-0 or ppp-0” as WAN interface
- Select “Increment” as LAN IP address spoof method
- Click on Apply to apply the settings
- Now enable ZIPB, by clicking on the Enable button.
- As last select the pc from the list. And click on Apply.
- Do an ipconfig /release and then ipconfig /renew (in a DOS box) on
the pc that you have selected in the list. The pc will get a WAN IP
assigned.
Once the device has retrieved the public IP address via IPCP, the ZIPB process creates a
spoofed IP address and assigns this address to a virtual interface attached to the device’s
LAN interface. The LAN side DHCP server is updated to allow the selected PC to obtain the
public IP address and public DNS server addresses on the next DHCP lease renewal.
Click on the Disable button to disable ZIPB again.
