hi

i want to access my network ont/onu on my local computer which is connected to ether2

eth5 is connected with olt GE input (image attached)
but i did not want to access all the onts through pppoe ip because i am also giving internet to user from other isps which is not through my mikrotik that isp input is directly connected to olt.

how to access giving them local ip without internet on same Ether5 port

can i apply pppoe/dhcp on same ether5 port to achieve this goal.
like i need to create two wan inside ont
1) static private mikrotik ip for ont access
2) pppoe of other isp not from mikrotik server
and enable Remote in ont
3) VLAN based will be also ok for me

Thank you
