routing problem with hotspot in this scenario.

RouterOS Forwarding Protocols

Hi
I have a network (some subnets) same this:

That all routes are static.
The routes for router (SXT) “A”:
Dst:192.168.1.0/24 Gateway:172.15.0.1
Dst:192.168.2.0/24 Gateway:172.15.0.2
Dst:192.168.3.0/24 Gateway:172.15.0.3
And this SXT (“A”) is DHCP server for that ether1. It give 192.168.0.5-192.168.0.254 to clients with gateway:192.168.0.1 and DNS:4.2.2.4 and 8.8.8.8

And routes for SXT “B”,”C” and “D”:
dst: 192.168.0.0/24 gateway:172.15.0.4
So far everything is good.
ether2 IP of RB750: 192.168.0.4/24 (it connected to network switch)
ether3 IP of RB750:193.168.1.2/24 (it connected to internet modem)
the hotspot will run on ether2 of RB750.

Now I want setup and configure a hotspot with RB750 for the network that connected to ether1 of SXT “A” (192.168.0.0/24) and I have a problem.
What is the best route for SXT “A” and RB750??
When I add:
dst:0.0.0.0/0 gateway:192.168.0.4 to SXT “A” and
dst:0.0.0.0/0 gateway:193.168.1.1 to RB750
Hotspot not work. Please Help me to add best route to this scenario.

Are you trying to bridge the two connections? If so, are the hotspot and the SXT-A Ethernet-interface both added to a bridge?

Or are you trying to actually route the packets… If so, where are the hotspot and it’s clients getting their IP addresses? DHCP will not reach beyond the SXT-A unless it’s acting as a DHCP relay.
