RouterOS Beginner Basics
1

I have ISP and 5 public static IP.
It using PPPOE client.
Where i have to add IP?

I was able to configure Mikrotik like pppoe client. I have internet but and i did NAT.
How I can manage other Public IP.
Where i have to add this ip?

And for example i have public IP 92.xx.xx.2 and i would like redirect port 80 to PC 10.0.0.11
Second Public IP 92.xx.xx.3 and redirect port 80 to the pc 10.0.0.12 ?

How to do this on mikrotik with PPPOE client.

Dont have to use it. Only if you have a server that also need publick ip? Normaley would be ok if you use one ip and route rest of trafic through Mikrotik with nat.
