Hello dear friends.

A client of mine have an ISA server with a real IP (WAN) address enabled on it, he can access RDP (Remote desktop connection) from international to this ISA. i will put a mikrotik server before the ISA, in this way the real ip will be on the mikrotik, the ISA will take its main ip from the next local ethernet adapter that is on Mikrotik server. Till now everything is ok even ISA already have the internet from Mikrotik now, but the main issue is that, how i can create a NAT rule in Mikrotik so that this client will login to ISA RDP (Remote desktop connection) via Mikrotik real ip address. Is this available with Mikrotik 2.9.27 ?.

Any suggestion help would be appreciated and thanks for reading.
If also any help available please mail it to: info@protechzone.com
Thanks again

it is available in RouterOS 2.9.51 and 3.14

Why are you using this old version? You need to upgrade to do what you want to achieve.

Thanks Chupaka i used the folowing:

chain=dstnat
Protocol=6(tcp)
In.Interface=ether1(local adapter)
action=dst-nat
To Address: 192.168.200.2
To ports: 3389

It worked yes, but whenever i enable this NAT, the internet connection being down

upgrade to one of mentioned versions (2.9.51 or 3.14) and then come back if you still have a problem
