Previously I wrote about configuring a Microtik for RDP. Well, that router died, so I’d to do it all over again. (Here are the Terminal commands, except I’ve changed my public IP address to x.x.x.x.):- /ip firewall nat>> add chain=dstnat action=dst-nat to-addresses=192.168.1.243 to-ports=3389 protocol=tcp dst-address=x.x.x.x dst-port=3389 log=no log-prefix=”” /ip firewall nat>> add chain=srcnat action=src-nat to-addresses=192.168.1.254 to-ports=3389 protocol=tcp […]
