I have a new ups that is controlled from a Windows 2003 server. I have a PC that is running v4.16 Mikrotik. This pc is connected to ups.
I need to know how to allow Mikrotik to communicate with the ups that is connected to server pc.

Kind Regards
Preggie Pillay

U mean u need to Check the inside UPS from outside the Network:
If so, IP/FIREWALL/NAT
chain=dstnat action=dst-nat to-addresses=(ADDRESS OF UPS) to-ports=(PORT OF UPS)
in-interface=(REAL INTERFACE) dst-port=(PORT OF THE REAL INTERFACE) protocol=tcp dst-address-type=local
