NMAP and firewall only IPS Monitor profile

[rramoa]

Hello good evening dear friends, we have an issue with the nmap command nmap -sV -p 161 but we have a segmentation firewall which the destination is there, currently we only have the ips in the security profiles but as a monitor, but it still appears like this filtered instead of open, do you know the reason?

Thanks

Hello

I tested the same and obtained the same result, and my firewall was not blocking the traffic.

I think this is just a normal behavior since NMAP shows filtered when there is no response from the server.

Keep in mind that the "closed" response is when the server returns a response like "connection refused".
