Firewall communication issue

Ge Qu — Tue, 12 Mar 2019 09:00:35 GMT

Hi,

I have Nagios resides in the firewall DMZ with security level 99, and want to monitor the inside interface which has security level 30, but I am not able to.

I am kinda new to firewall, i am not sure if this is something to do with the firewall's security level or the nature of the firewall?

Thank you.

On the ASA you have to access

On the ASA you have to access the nearest interface which is the DMZ interface in your case. It's by design of the ASA that you can't access remote interfaces.

Hi Karsten,

Hi Karsten,

Thank you for your reply.

So what you mean is, if my nagios is resides in DMZ, and i cannot reach out the inside interface to check the firewall status, by design, i need to check the DMZ interface to check the firewall status?

Did I understand you correctly?

Yes, that's exactly what you

Yes, that's exactly what you have to do.
