156-215.81.20 SIC and SmartConsole Management Practice Question
A security administrator is configuring a new Security Gateway in SmartConsole. The gateway is behind a NAT device and its internal IP address is 10.1.1.1, but it communicates with the Management Server over the internet using a public IP address of 203.0.113.5. The administrator needs to ensure that SIC and policy installation work correctly. What should be configured on the gateway object in SmartConsole?
⚠ Common exam trap
The trap here is assuming that simply setting the public IP as the gateway's address is sufficient, without considering that the gateway's actual interfaces use the internal IP and that NAT must be enabled on the gateway object.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set the gateway's IP address to 10.1.1.1 and enable 'IP Address is NATed' with the public IP 203.0.113.5.
When a gateway is behind NAT, the gateway object in SmartConsole must reflect the internal IP and have the NATed public IP configured. This allows the Management Server to use the correct address for SIC and policy installation. The 'IP Address is NATed' option ensures that the Management Server communicates with the gateway using the public IP while the gateway's internal configuration remains unchanged.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Set the gateway's IP address to 10.1.1.1 and enable 'IP Address is NATed' with the public IP 203.0.113.5.
Why this is correct
Configuring the gateway's main IP as the internal address and enabling NAT with the public IP allows the Management Server to use the correct address for SIC and policy installation. The Management Server will use the NATed address when initiating communication, ensuring connectivity through the NAT device.
- ✗
Set the gateway's IP address to 203.0.113.5 and disable NAT on the gateway.
Why it's wrong here
Setting the gateway's IP to the public address and disabling NAT would cause the gateway to use the public IP on its internal interfaces, which is not the case. The gateway's actual IP is 10.1.1.1, so this configuration would be incorrect and break communication.
- ✗
Set the gateway's IP address to 203.0.113.5 and configure NAT on the gateway.
Why it's wrong here
Setting the gateway's IP to the public address would cause the Management Server to attempt communication to that address, but the gateway's internal interfaces use private IPs. This would break routing and SIC unless additional configuration is done, which is not the standard approach.
- ✗
Set the gateway's IP address to 10.1.1.1 and configure a static route on the Management Server to reach 203.0.113.5.
Why it's wrong here
A static route on the Management Server does not solve the NAT traversal issue. The Management Server needs to know the public IP to reach the gateway, but without NAT configuration on the gateway object, SIC will fail because the gateway's certificate will not match the expected address.
