Can the MID server access CIs on different network segments?

Makoto Uchiyam1 · ‎07-15-2022

Hi.

Please tell me if it is possible that the MID server access CIs on different network segments.

When we set the IP range, we set a private IP address, but we thought that if that were the case, we could only detect CIs that existed in the same network.

Regards,

Sorry for my poor explanation.

I have no idea about the networking requirements of the MID server and the target server.

My questions are following four points.

1. Is it possible to access a server on a network beyond the router by specifying a private IP address?

2. If possible, is that predicated on having router credentials?

3. What happens if some devices have duplicate private IP addresses?

4. Is it possible to do Discovery from a MID server in the public Cloud to our own data center?

Hi Makoto,

1. Is it possible to access a server on a network beyond the router by specifying a private IP address? Yes, if required firewall rules are granted, you can do discovery with network subnet like 10.x.x.x/22 with private IP

2. If possible, is that predicated on having router credentials? Yes, router has to be discovered as well so credentials will be required

3. What happens if some devices have duplicate private IP addresses? Discovery mostly identifies using serial numbers (hardware related CIs), Installation paths (for software related CIs). So it will discover all and identify them uniquely. Having similar IP will not be a problem

4. Is it possible to do Discovery from a MID server in the public Cloud to our own data center? That will require a whole lot of permissions and it is not advisable. It is much easier and better in terms of performace to have a MID Server in your own datacenter as well

If the required firewall rules are done to allows access to the other network segment. It is definitely possible but it is not advisable due to traffic issues.

It is advisable to have a MID Server in every segment.

Hi suvro,

Thanks for your reply!

I understand Q1, Q2 and Q3.

Regarding for Q4, I can't imagine how that is possible, because there is internet between public cloud and private data center. Is it realized by detecting routers in the data center that have a global IP and then set a private IP address to the IP range?

I am not trying to achieve this with my project, I want to understand the requirements of connection between MID server and target servers.
