How to set up a second server to access the network from another IP?

Question

Network administration

Prompt pzhlsta, there are 2IP addresses of static.
For all the years of work, I have always used one ip, and now I want to try using another ip that the provider provided, but I don’t know how to do it right.
What I have: SNR equipment provider
Kerio software, SNR switches for LAN, domain controller.
There is another server machine but it is not used and I want to bring it to the Internet on the second IP address, how can I do this, but to secure the main network?
In theory, I see it like this: I throw another WAN cable from the SNR provider, I prescribe a second IP, mask, gateway on the network card and you're done?

Answer 1

The server on which you plan to hang ip must be connected to the local network?
In general, the actions depend on the structure of the network. In general, your option is working, but if the server is still connected to the local network, then you need to write routes on the server.

Answer 2

Is the router connected to the provider able to hold several IPs?
Maybe you have a gateway where you can organize this?
In fact, you need a device that looks at the provider with one end, and the network with the other. And now on it you are already setting up the output of internal servers to the external server under the desired IP
Option that you think is working of course, but not comfortable. I would say mauvais ton.
But if you don't want to bother, then two network cards for each server. One on the outside, the second on the inside. Set a static route to the internal network.
But as I said, it's not very smart to do so.

Answer 3

Tell us more about the 2nd IP. Is it a dedicated line? Or on the current some other type of connection or something. About this, you can consider options and whether they exist at all.
