Public IP server natted on internal subnet

RouterOS General
1

Hi all,

I have, actually, this configuration:

LAN (172.18.0.0/16) —> some wireless PTP —> CCR 1032 with on a interface a subnet 192.168.251.0/24 (where there are all servers) and NAT 1:1 of a public ip (217.19.154.186->192.168.251.10).

Now, if I want to reach the server from LAN as if it was outside how I can do?

If I force out and in interface on 1:1 NAT obviously it stop working. But I also have fear that natting the public IP on all interfaces is someway wrong.

Thank You!
