How to setup PPPoE Wan port forward manually?

[BlueGrass]

Dear all,

We are running R81.1 Gaia OS for the CP6000 Machine in Standalone mode.

And one PPPoE wan is connected to this Firewall with a Dynamic IP address

I wonder if I can set up DNAT on the wan interface to port ward the Wan: 12345 TCP to 192.168.1.123: 4444 port ??

Please show me the step if we can do that as well

For the translated source in NAT sometimes you can get away with a host object (0.0.0.0) to pickup the Dynamic address.

Not tried it with DNAT however there is also the "LocalMachine" object.

Are you planning to leverage DynDNS or similar?

[BlueGrass]

No, DDNS is not an option yet.

Actually, we are using Cloud managed Firewall Embedded Gaia, the Local Machine object will be always presented as "100.X.X.X" IP. I am not sure if the "LocalMachine" object will work in this case.

6000 series are not running embedded Gaia reserved for SMB/spark appliances, please confirm the appliance model?

Both 

1570 and 6000 are also using.

What you're talking about is the "Main IP" of the object representing the security gateway.
LocalMachine resolves to the leading IP on each interface of the gateway.
Thus: it should work.

Tried and worked, thanks.
