Join two subnet - Different range - two Mikrotik

RouterOS Beginner Basics
1

Hi,

I am using a main router Mikrotik for daily use, 192.168.150.0/24. After I have another router Mikrotik connected on a switch on same net but this new Mikrotik has wifi and his subnet is 192.168.88.0/24 (this is the cause for that I want to connect this new Mikrotik)

If I connect to this last Mikrotik (wifi) I can do ping 192.168.150.0/24 without problem, in this subnet there is a printer, but I can’t do ping from 192.168.150.0/24 → 192.168.88.0/24.

I want to join both subnet to use the printer which uses Wifi and main Mikrotik Router hasn’t Wifi.

Thanks

You need to tell both routers where the “other” LANs are.

192.168.88.0/24 router already should have a default gateway (0.0.0.0/0 route through its 192.168.150.x IP address) and that’s the reason you can ping 192.168.150.x addresses while connected wirelessly.

You need to tell the wired router, how to reach 192.168.88.0/24 network; let’s say wireless router IP on .150 range is 192.168.150.254:

/ip route add dst-address 192.168.88.0/24 gateway=192.168.150.254

Hi,

Thanks you for fast reply.

I created that route but I can’t reach that subnet. (I can ping wireless router - 192.168.150.58)

$ ping 192.168.150.58
PING 192.168.150.58 (192.168.150.58) 56(84) bytes of data.
64 bytes from 192.168.100.58: icmp_seq=1 ttl=64 time=0.219 ms

Router is created on wired router → A S 192.168.88.0/24 192.168.150.58
And its reachable.

Here a traceroute log:
$ traceroute 192.168.88.200 (printer)
traceroute to 192.168.88.200 (192.168.88.200), 30 hops max, 60 byte packets

Please issue on .150.1 router and copy & paste results:

/ip export

Sorry for late reply. Here export main router (150.1)

/ip firewall nat
add action=masquerade chain=srcnat
/ip route
add distance=1 dst-address=192.168.88.0/24 gateway=192.168.150.51 (IP that main Router gives wireless router)
/ip route rule
add dst-address=192.168.150.0/24 src-address=192.168.88.0/24 table=main

I try creating that router that if I (connected with IP range 150) can access subnet .88 throught 150.51 (IP router wireless), isn’t it?

thanks.

I asked for a full /ip export. Editing out details won’t help; shooting this blindly…

/ip firewall nat
add action=masquerade chain=srcnat

First action that needs to be taken: modify that src-nat rule, specifiying the output (WAN) interface.

/ip route
add distance=1 dst-address=192.168.88.0/24 gateway=192.168.150.51 (IP that main Router gives wireless router)

On previous post you wireless AP IP was 192.168.150.58, on this export is .51???

/ip route rule
add dst-address=192.168.150.0/24 src-address=192.168.88.0/24 table=main

Remove that.

Hi,

Im sorry for changes but I was changing some values and for that motive the IP has changed, I need delete some values from full export for security.

Finally I solved creating what you said me in first post:

A rule on IP → route to reach subnet 88.

192.168.88.0/24 192.168.158.58 (IP that main router mikrotik gaves to wireless router)

Thanks.
