how to do port forwarding

[munaf]

how can i do port forwarding for specific port on mx64 device

[rhbirkelund]

Go to Security & SD-WAN -> Firewall, and scroll down to "Forwarding rules" section, and press "Add a port forwarding rule".

There you enter a description, what uplink port it should apply to, protocol, the public facing port, LAN ip, LAN port, and who should be allowed to use it.

In the below example, the rule is applied to both WAN links, and the public facing port, is forwarded to port 80 on machine with IP address 10.10.10.10

how can i check after adding this rule whether this ports are open

Not really in the Dashboard, no.
But you could try and browse your way to the public IP of the MX and see if the webpage is served. Or use a tool like NMAP, to scan for open ports.

Make sure your upstream modem/router isn't NAT'ing either, else you'll need to configure the port forward on that device also.
