IP redirection to local machine

[bjohn]

In my work environment, there is software that connects with a server at a client location to send data. The function performed by the client server planned to be moved to a VM that resides on our local network.

Is there a way to use IP alias and or NAT rules to redirect traffic sent to this outside IP to an internal IP on our network?

pfSense is the router/firewall. The sending IP is hard coded in the software and we have no way to contact the original programmer.

Thanks

This can be done by NAT 1:1 if the client and the server are connected to different network ports. If that isn't given you can put the VM in a vLAN.

not sure why you would need 1:1 nat, simple port forward should work for this.

Yes, just a port-forward with LAN as the interface instead of the usual WAN.
