Please help.
I would like to connect from the Internet to a computer on an inner subnet through RDP. The setup is as follows: Mikrotik Router leases 10.70.70.251 IP Address to an Edge Router-X. The computer to be connected to has been given an IP 192.168.1.100 by the Edge Router X DHCP. I have created a port forwarding on the Edge Router with outside port 5100 and forwards to port 3389 of IP 192.168.1.100. Remote connection is also allowed on the target PC.
On the Mikrotik, I have done:
1. ip firewall nat
chain=dstnat dst-address=”PUBLIC IP” dst-port=5200 protocol=tcp \
action=dst-nat to-addresses=10.70.70.251 to port 8585.
2. ip firewall nat
chain=dstnat dst-address=”10.70.70.251 dst-port=8585 protocol=tcp \
action=dst-nat to-addresses=192.168.1.100 to port 5100.
On the PC trying to connect via RDP, I have entered the Public IP then : 5200 as the IP/port and the computer username. I had done this setup before and it worked but I cannot remember how I did the port configuration. Can’t get it to work. Thanks to assist.
