You should do the following to change the Web management port. / ip service set www port = 80 address = 0.0.0.0/24 disabled = no. You can do the NAT process in this way. /ip firewall add action=dst-nat chain=dstnat comment=“Web Server” disabled=no dst-port=80 protocol=tcp to-addresses=192.168.1.50 to-ports=80
