Hi i need help to connect two different subnet on my mikrotik CCR2004-16G-2S+PC router
all of interfaces is connected via bridge 1 :
i want to connect this
192.168.87.0/24 to 192.168.88.0/24
and
192.168.88.0/24 to 192.168.87.0/24
please help
thanks so much
I always thought when a device has been setup properly with it’s own address on the interface to be used, the routing rules are added automatically.
You may want to give a bit more context on what you’re trying to do (drawing of a network diagram may help a lot) but more importantly, how is your device configured right now ?
Terminal: /export file=anynameyouwish (remove serial, public WANip, etc.)
Post between code quotes for readability.
there are two rooms let’s say Room A and Room B
Room A has ip address 192.168.88.1/24
Room B has Ip address 192.168.87.1/24

Something is not correct on that drawing.
The two devices you use to provide the wireless link, they both have 192.168.88.1/24 as address, which is in the same range as room A ?
That can not be correct.
Which device acts as router between “room A” and “room B”.
Is there something on the left antenna acting as router for both ?
The export you provided is from CCR ?
Because on your drawing I see 3 Mikrotik devices (and yes, I know CCR is not an antenna 
).
Their config can be needed as well.
I assume (but can be wrong) the CCR router is the one in the room on the left ?
Please add their names, so it becomes more clear what is what.
If everything passes over CCR, please indicate what ports those antenna’s are connected to and where local LAN for room A is connected to.
Speculating here with respect to your requirements …
You have two locations which both have a WAN connection.
You want to make sure both locations can communicate with each other.
Then (simply speaking) you need to add a tunnel between both locations (and depending on how the answers are on the above questions it can be dead simple using routing, or something a bit more advanced using EOIP, VPN or alike).
Does that sound correct as requirement ?
PS I’ll wait for your answers. Already had a quick look on the config and to be honest, can’t really make sense out of it.
I also hope that device is not directly connected to Internet since there is no firewall ?
Yes you are correct the device who act as router which is mikrotik CCR is on the left (Room A)
here is my correction of drawing hope you can make sense of it
my laptop connected to mikrotik is connected to internet
antenna = ether 8
local lan connected via wifi akses point on ether 12
No only on Room A on mikrotik has Wan connection, i want to make sure the LAN network with ip address 192.168.87.2 - 192.168.88.254 can communicate
