A network administrator is deploying a new Cisco Secure Firewall Threat Defense (FTD) firewall After Cisco Secure FTD is deployed, inside clients nave intermittent connectivity to each other. When ... the packet capture on the Secure FTD firewall, the administrator sees that Secure FID is responding to all the AW requests on the inside network.

Show Suggested Answer Hide Answer
Suggested Answer: A

If inside clients have intermittent connectivity issues and the Cisco Secure FTD is responding to all ARP requests on the inside network, it indicates that there may be an incorrect proxy ARP configuration in the NAT policy. Proxy ARP can cause the FTD to respond to ARP requests on behalf of other devices, leading to connectivity issues.

Steps to resolve:

Review the NAT policy on the FTD to identify any incorrect proxy ARP configurations.

Disable the proxy ARP setting for the relevant NAT rules that are causing the issue.

This ensures that the FTD only responds to ARP requests as needed, preventing it from interfering with normal ARP traffic on the inside network.

I’d try option D, transparent mode could solve the problem.

Ah, I see the key is to identify why the FTD is responding to all the ARP requests on the inside network. Reviewing the NAT policy and disabling any incorrect proxy ARP configuration seems like the way to go.

Converting the FTD to transparent mode could work, but I'm not sure if that's the best solution. I'll double-check the other options first before considering that.

Hmm, hardcoding MAC addresses on client machines doesn't sound like the right approach here. I think I'll focus on reviewing the access policy and making sure ARP is allowed between the inside clients.
