:D Finally!, that worked. I definitely have some reading to do, I still do not quite understand why that worked. But thank you very much for the help! add action=dst-nat chain=dstnat dst-address=10.20.8.9 in-interface=ether1 \ to-addresses=172.16.4.52 add action=src-nat chain=srcnat dst-address=172....

Still not working completely, but have to be making progress. I made the changes you suggested and now I can see packets hit both of the firewall rules. But when I look at the connections tab a tcp connection will never establish, it just says sync... here is the changed code. add action=dst-nat cha...

no there is no ISP..(all private network) 172.16.4.52 is the current ip of the "Modbus gateway" device. No DHCP as all ip defined are static. I just need to be able to type 10.20.8.9. in my browser and hopefully it should act as if i was on the 172.16.4.xx subnet. so.. "MY PC (10.20.8...

add address=10.20.8.9/24 interface=ether1 network=10.20.8.0

so I made that change and I can now successfully ping 10.20.8.9 but the NAT rules still are not working.? and if I try 10.20.8.9 on port 80 it just brings me to the routers webGUI. Not to the 172.16.4.52 WebGUI.

hopefully I am answering this properly, a PC with an address of 10.20.8.71 should poll -10.20.8.9- and expect the same results as if i was polling 172.16.4.52 directly on the same subnet.

thank you for the quick responses.

Greetings, Let me start by saying I have probably read every post concerning RouterOS NATTing and for some reason I cannot get it to work. I have been at this for like 4 days now and finally decided to post a request for some help. I am a process control guy, I love route-able IP ranges, so much eas...
