Set the Host Name to that given to the firewall in your DNS server. Once you have completed Network Information, apply the changes by clicking on the Save. The GB-750 will now be on a different logical network (assuming you’ve changed the default IP address for the Protected Network) and you will not be able to access the GTA Firewall from your workstation, since the firewall will now be on a different network. -

Page 24: Troubleshooting Q & A
• Have you added a static route to the GB-750 to tell it which router is used to reach the problem network? Have you set the router’s default route to be the GB-750? Have you set the default route for hosts on the problem network to be the router? •... - Page 25 6. Why can't I see or ping the Protected Network interface? You may have the wrong cable for your connection. • For a direct connection (GB-750 to host or router) you need a cross- over cable. • For a connection to a hub or switch you need a straight-through cable.
- Page 26 A new GB-750 has two identical slices. When the GB-750 is upgraded to a new runtime, the upgrade process auto- matically overwrites the memory slice not in use with the new software version and the existing configuration, leaving the production firewall version and configuration intact.
