Below is the configuration to turn off port forwarding:
[admin@MikroTik] /ip firewall nat> print
Flags: X - disabled, I - invalid, D - dynamic
0 ;;; NAT
chain=srcnat action=masquerade log=no log-prefix=""
1 ;;; win2016
chain=dstnat action=dst-nat to-addresses=223.255.255.12 to-ports=3389
protocol=tcp in-interface=all-ethernet dst-port=3389 log=no log-prefix=""
2 chain=dstnat action=dst-nat to-addresses=192.168.88.13 protocol=tcp
in-interface=all-ethernet dst-port=80 log=no log-prefix=""
[admin@MikroTik] /ip firewall nat>
I don't understand a bit. When in-interface=all-ethernet is selected, if all-ethernet is replaced by in-interface=pppoe1, the forwarding cannot be successful. Directly invalid, what is the reason? ROS version is CHRx86_64 v6.49.7.Trouble the engineer teacher to point out the reason for this
