Not able to discover firewall devices in ServiceNow PROD

[sathishakumara]

Hi Team,

I am facing below issues while dicovering firewall devices. 

1. MID Server mid.server.xvvd_Mid_Server_Prod is not suitable because it does not have the required capability: Nmap.

2. xx.xxx.xx.xx is not a reachable host (no response to target ports scanned by MID).

Please let me know what is the reason to get above message.

We tried to discover with actual MID server but still end up getting above errors.

we tried to trouvleshoot with firewall with SNMP credentials but still getting above messages.

Hello @sathishakumara , NMAP is used for Credential Less discovery, and it should be installed on Mid Server if you are planning to do so. If you aren't planning for credentialless discovery, then go to sys_properties.list and set the property: mid.discovery.credentialless.enable to false (if its not present then create a new one with false value). 

Make sure that mid server capability is set to All. Also, ensure that the IP you are trying to discover is reachable, valid credentials are configured in your instance.

Hi  @sathishakumara ,

Could you pls check if the port 161 is opened for these devices? Since the system is trying SSH credentials i am hoping port 22 is opened. If not required for other purposes, you might want to talk to network team and close the port 22 and get the port 161 opened.

Please Accept the solution if it assisted you with your question & Mark this response as Helpful.
