Best ideas for giving ip addresses to 3 networks

Hi i have 3 dsl circuits all with with ip addresses routed to the first bridge ip address from my provider
So it looks like this and all the bridges have the same gateway

Bridge 1 208.XXX.XXX.52/24 Gateway 208.XXX.XXX.1
DSL1 76.XXX.XXX.64/28

Bridge 2 208.XXX.XXX.53/24 Gateway 208.XXX.XXX.1
DSL2 76.XXX.XXX.128/28

Bridge 3 208.XXX.XXX.54/24 Gateway 208.XXX.XXX.1
DSL3 76.XXX.XXX.168/28

I have a routerbooard v3.30 with 5 ethernet ports and 1 wlan1 port

I have 3 clients that each have a routerboard and wireless card in them on the remote ends

Those clients are connected to my routerboard via the wlan1 port

I want to hand out public ip to the customer routers plugged into their routerboards on ether1 on the remote sides, each customer assignment 1 of the DSL connections.

My question is can i do this on the one routerboard even though all of my bridges have the same subnet of /24 on the same network

And what would be the best way to approach this solution

The hands down best way to do this is to ask your provider for a /30 for your router, and to route /28s across it. The /30 would be in a different /24 than the space routed across it. That way you can just do whatever you want with the customer IP space the ISP gives you. This may be made impossible by the fact that many DSL providers forbid resale.

You can’t use proxy ARP as you’d screw everything up for everyone else because you don’t own the whole /24. You can’t just implement /28 IP addresses because then you wouldn’t have a default gateway on that network.

It’s early in the morning, but if you want to directly use those IPs behind the RouterBOARD you’re going to have to have it act as a bridge, and not as a router.

Even if there is some other solution, it’s best to get a reseller account and just get routed space.

I do have a reseller account for the dsl accounts, and with the routed account to the bridge to the network it routes the /28 from my network to thier network. It allows me to host the gateway for the /28 on my side and uses a single static bridge to get to the isp side.
Couldnt i split up the 3 /28 into 6 /30s and route to my customers 1 hop for the router from me to them. With the

Can you draw a network diagram with all network interfaces and their respective IP addresses?

Sure here is a pic of what im trying to do, i dont have any ip stucture in place to the clients yet, im wondering what the best way to do that would be here is the pic , and the ip info thats on the modems is actually just representing what each modem is assigned to and the info needs to be assigned to the routerboards from the respectiful modems as the modems are just bridges and hold no ip info

If the bridge IPs are on the same /24 as the /28s what I said initially applies, and they’re not really routing anything to you.

If they are not, just assign an IP address of the /28 on the inside RB interface and use the rest on the customer router outside interfaces.

Im gona post my solution to this problem , i tried everything from policy routing to local routing and nothing seemed to seperate the traffic from the dual gateway problem, so what i did was put ether3 ether4 ether5 and wlan1 on a bridge on 1 mikrotik, then gave each dsl its own mikrotik, then i used pppoe on the mikrotiks that had the dsl on them , so 3 pppoe servers and seperated them out with different servicenames in the pppoe-server section and client section. Since i had pppoe clients at each of the remote clients i just had the clients put in the service names for each of them and then the corrosponding pppoe server handed them out thier correct ip address and wala . 3 different providers

Client 1 wlan connected >> Mikrotik router 4 Wlan bridge router ether3 >> Miktorik router 1 hosting dsl from provider 1 hosting pppoe, service name=service1
Client 2 wlan connected >> Mikrotik router 4 Wlan bridge router ether4 >> Miktorik router 2 hosting dsl from provider 2 hosting pppoe, service name=service2
Client 3 wlan connected >> Mikrotik router 4 Wlan bridge router ether5 >> Miktorik router 3 hosting dsl from provider 3 hosting pppoe, service name=service3

Policy routing would have used less devices but i stil could never get it to work ty all for the replys
