Hi Everyone, i am hoping to get some guidance on something which should be quite simple but I just could not figure it out. You can consider me a beginner in network routing configuration.
My apartment has a 4 ports hub provided for the unit.
From my ISP modem, i connected it to my Mikrotik hap ac3 router WAN port on port 1.
I have another router - “ROG Rapture GT-AX6000” connected to port 2 of Mikrotik.
This ROG router is used to serve Wireless and other smart devices for my home.
For port 3 of my Mikrotik, I connected it to my personal PC located in another room which is considerably far from my ROG router.
The 2 remaining ports are unused.
This is a very simplistic diagram of how my home network is currently being connected.
I did some initial basic configuration to get internet working for both 192.168.88.0/24 and 192,168.86.0/24 network.
However, from my PC ‘192.168.88.253’, i could not reach my ROG router on 192.168.88.252 or 192.168.86.1.
I can only access my ROG web management portal by connecting to the wireless network or directly plugging into the port interface by ethernet cable.
I have added a firewall rule to allow the traffic to flow from 192.168.88.0/24 → 192.168.86.1 but it does not work.
Do I need to configure a VLAN for this to work? Or should I define some add some specific routing rule?
What I want to achieve:
To be able to connect from 192.168.88.253 to my ROG router management page.
To allow specific devices in the network 192.168.86.0/24 to be able to connect to 192.168.88.0/24 as I plan on setting up a NAS server on this network range.
The below is the configuration export.
