Installed firewall in my jaunty

This is the link I used to make firestarter run everytime I log in my Ubuntu 9.04 (jaunty jackalope)

The configuration:
1. Laptop with the ff. connections:

• ppp0 - huawei e160 usb modem of Sun Cellular,
• eth1 - laptop's built-in wifi
• shared internet connection, dhcp server (c/o Firestarter)
  

2. Windows laptop, also on wifi, able to access the Internet via laptop1

The problem: kept running into Firestarter error message - cannot start firewall - when I turn on DHCP for eth1

The solution:

• Manual IP address/subnet assigned to laptop1's eth1
• Reinstalled the dhcp3-server package (in synaptic package manager)
