How to redirect traffic from client PCs when ip address changes?

Question

Mikrotik

Hello!
The company operates a billing system, to which client machines (about 300 machines) are connected using its IP address. The client machines and the billing server are located on different subnets for security reasons. Between them Mikrotik CCR. The other day we decided to transfer billing to the cloud. Accordingly, it (billing) will now be available at a new ip-address, and to connect to it, you need to change its ip-address on all clients. Question: is it possible to carry out any manipulations on Mikrotik in order to save the settings on client machines? For example, how to redirect traffic to the cloud somehow?

Answer 1

This should be asked from the one who implemented billing before. Or ask billing technical support

Answer 3

As an option - pin the old address of the machine to Mikrotik and natit it into the new billing ip.

Answer 4

See the answers to these two questions. In your case, the same is done.

• How to send incoming packets on Wan interface back through Wan to another IP address?
  
• How to redirect traffic from one DC to another?
  

It is not required to change the address on Mikrotik, because you say that the route to the old billing went through it anyway, so everything should work smoothly.
