Access bridge settings from devices in LAN

RouterOS Beginner Basics
1

Hello.
My ISP provides internet using GPON and I have to use ONU Terminal (not SFP module) to get the internet to my RB4011. Internet connection scheme is: ISP->ONU Terminal (in bridge mode)->(ether1)RB4011(bridge with ether2-ether10)->Clients. My ONU Terminal has only bridge mode and the only way to configure it is connecting to its ethernet port directly from a PC and access web UI with 192.168.1.1. I cannot access its configuration when connected through RB4011. How can I solve this? Current RB4011 config attached.

Problem: Your Router AND your ONU Terminal have the IP-Address 192.168.1.1
So you will have to change the IP-Address of at least one device

I have already done it, no result (no response on 192.168.1.1) since ether 1 (to which bridge is connected) and other ports are not in one bridge. Config with changed address:
RB4011.rsc (4.89 KB)

Solution A:
If it’s possible to change the IP-Range of the Router completly
192.168.12.1/24 insteed of 192.168.1.1/24

After that everything will work…


Solution B: Add Route
This might help ! if not you will need mangel rules…

/ip route add copy-from=[find where dst-address=0.0.0.0/0] dst-address=192.168.1.1/32

Solution C: Route + Mangel
If Solution B doen’t work, try this :

/ip route set [find where dst-address=192.168.1.1/32] routing-mark=ToUno

/ip firewall mangle
add action=mark-routing chain=prerouting dst-address=192.168.1.1 new-routing-mark=ToUno passthrough=yes

Changing the IP-Range is not possible. Solution B and C didn’t give any result, still no response on 192.168.1.1.

I can’t really believe that you can’t change LAN IP addressing scheme, but you know better. However, without changing it (and I guess you don’t have enough rights to change addressing of ONU) your problem can not be solved without extensive tinkering.

Changing the IP of ONU is possible, however I had to do some research to find out the way to do it. Changed ONU’s address to 192.168.3.1 and added the address 192.168.3.2 on RB4011 for ether1. Now I am able to access web UI. Thank you for your help.
