our set-up
ISP--modem-------router----------------mikrotik RB600----ethernet2
I I I I
PPOE WAN=PPOE WLAN ether2=192.168.0.254/24
LAN=192.168.2.1 netmask=255.255.255.0
NETMASK=255.255.255.0
MODE=DHCP

What must be our configuration for ETHER1 of POE port in order for us to access the internet? Please reply immediately. Thank you very much and more power!

That is such a basic configuration that is even described in the Mikrotik Manual.

Remember just one thing. When you establish PPPOE connection, you set all routing on PPPOE interface, not physical interface pppoe is set on.
