Home network setup with 2 MikroTik routerboards

RouterOS General
1

Hello,
I would like to ask you for help with home network issue.

My network is described at attached picture. Router A is providing connection to the Internet.

What works correctly:

  • PC has access to the Internet


  • Phone has access to the Internet


  • Phone has access to NAS

What doesn’t work:

  • PC cannot access to NAS


  • Phone cannot access to PC

Please, help me how to setup routers so each device can see each other. In other words how to create “one LAN”.

Thanks in advance,
Peter

In your case all solution is to add a static route to Router A who will have this:

ip route add dst-address=192.168.88.0/24 gateway=192.168.11.253 disabled=no

This will resolve your problem because when you try from PC to access NAS, Router A does not know path to your 192.168.88.0/24 and send all traffic to 0.0.0.0/0 (Internet) and when your phone try to access PC router B send the packet to 192.168.11.1 but when router A need to reply he find itself in same situation as before, don’t know where 192.168.88.0/24 is and send it again to 0.0.0.0/0 (Internet).

Thank you for response.

I added ip route to Router A

[admin@MikroTik master] > ip route print                                           
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 ADS  0.0.0.0/0                          10.235.19.201             1
 1 ADC  10.235.19.200/29   10.235.19.202   ether1                    0
 2 ADC  192.168.11.0/24    192.168.11.1    bridge1                   0

I can ping 192.168.88.1 (Router B) from PC, but I still cannot ping 192.168.88.251 (Phone) or 192.168.88.254 (NAS) from 192.168.11.252 (PC).
I can access shared folder on 192.168.11.252 (PC) from 192.168.88.251 (Phone)

IP route on Router B is following:

[admin@MikroTik wifi] > ip route print
Flags: X - disabled, A - active, D - dynamic, 
C - connect, S - static, r - rip, b - bgp, o - ospf, m - mme,

I added eth1 to the bridge on Router B and it is finally working.
