Routing Traffic between different subnets

I recently started reading regarding networking so I am new to this and also new to RouterOS. Previously I did some minor configuration in a OpenWRT router, but only through GUI.

In general what I am trying to do, is to use a Mikrotik router to “connect” two different networks. Below is my topology

Some notes

  • For all cameras in Network B, the server (192.168.88.1) is currently configured as gateway
  • Main router (192.168.68.1) is the DHCP Server for Network A
  • Network B uses static IPs

My end target is

  • Access any device in Network B from Network A
  • Devices in Network B, to be able to access the internet
  • Access Mikrotik router configuration interface (winbox) from Network A devices

What I did until now

  • Set wlan1 interface to “station pseudobridge” and connect Mikrotik to Network A wirelessly as a client
  • Set both wlan1 and ether1 as LAN
  • Removed bridges
  • Removed firewall rules

The problem is that:

  • I can only access Mikrotik router configuration interface (winbox) from Laptop 2 (Network B). It can be accessed from devices in Network A
  • Laptop 2 (Network B), and any device in Network B, does not have access to the internet

Below my routing configuration

Flags: X - disabled, A - active, D - dynamic, C - connect, S - static, r - rip, b - bgp, o - ospf, m - mme, B - blackhole, U - unreachable, P - prohibit 
 #      DST-ADDRESS        PREF-SRC        GATEWAY            DISTANCE
 0   S  0.0.0.0/0                          192.168.68.1              1
 1   S  192.168.68.0/24                    192.168.68.1              1
 2  DC  192.168.68.0/24    192.168.68.0    wlan1                   255
 3 ADC  192.168.88.0/24    192.168.88.0    ether1                    0
 4   S  192.168.88.0/24                    192.168.88.251            1

As I understand I need to set some static routes in Mikrotik, but whatever I tried until now it didn’t work. Any ideas? Any tutorial that addresses my issue that I should read?

Hi.

You need to add static route to the 192.168.88.0/24 network on your house main router pointing to 192.168.68.67 (and this IP has to be static for Mikrotik).

Correct the main house router is not aware of the 192.168.88.0/24 network and thus you need to tell it…
ip route add dst-address=192.168.88.0/24 gateway 192.168.1.5 routing-table=main ( assuming lets say 192.168.1.5 is the IP of the second router ).

Plus will need firewall rules in the forward chain that are applicable.
