4 – Troubleshooting 19
The GB-750 has three network interfaces; two are used for Protected and
External Networks. The other network interfaces can be defined as any of the
three network types: Protected, External or PSN (Private Service Network,
GTA's DMZ). Only External and Protected Network interfaces are required
to initially configure and test the GTA Firewall. See the

Network Information
Once you click Save on the Network Information screen you will not be able
to access the GB-750 from your workstation, since the firewall will now be on
a different network.
Re-configure Workstation
Re-configure your workstation back to its original IP address, now on the
same network as the GTA Firewall.
Access the GB-750
After re-configuring your workstation, you can access the GB-750 using the
new IP address assigned to the Protected Network interface.
The GB-750 should now be active and functioning in the default security
mode, (all internal users are allowed outbound and no unsolicited inbound
connections are allowed). You can now perform additional configuration tasks.
