Reboot and Test Connectivity:

Reboot and Test Connectivity:
- At the root prompt, type reboot:
- - root@Devil:~ # reboot
- Allow to reboot unattended.
- After it's fully up, hook up a laptop/internal PCs to the LAN switch
- Boot laptop/PC and do IP/connection tests
- - Does it get onto the internal network?
  - Type /sbin/ifconfig on the internal system (ipconfig for win)
  - Try ping 192.168.0.1
  - Try ping 216.239.37.99 (google.com IP)
  - Try ping google.com (by name)
  - NOTE: You should not be able to ping any machines in your DMZ. This is “a good thing” by default. If you want any access, then you will need to modify the /etc/init.d/firewall.rules file to open ports & services between the Internet and the DMZ (and/or internal services). This is a must if you want DMZ hosts to “get IPs” from the firewall's DHCP server (ports 67/68) or use the firewall's DNS (53).
