Network topology

Hi All,

I’m trying to design a new network topology for a small wireless network (wisp oriented). A centralized AP on 433ah will accept connections from SXT CPEs. Some CPEs will only have internet access, some others should also communicate each other (bridged interfaces) and will all have access to specific network resources i.e webserver behind AP.

I’ve managed to setup User Manager with success and I’m now wondering about the optimum network topology design for this implementation.

End user should have dedicated traffic limit for Internet access (i.e. 2mbps) and different limit for network resources (i.e 50mbps for the webserver). Is this manageable with queues implementation?

All CPEs should have a DHCP pool on lan interface like 192.168.0.10 -192.168.0.254 with gateway 192.168.0.1 (CPE lan interface IP). Which is the optimum solution to pass DNS IP on the end users? I mean routing technic.

I assume that I can use /30 mask subnets for each cpe communication with AP (CPE 10.0.0.2/30 & AP 10.0.0.3/30). Is there any other optimum and future proof solution on that?

Network diagram for a clear view:

Some corrections… The above diagram does not present /30 subnets for all CPEs connected.
I mean the PPPoE subnet will be dedicated with respective gateway.
Can I have a hybrid solution with PPPoE and /30 subnets (for special routing between CPE) on the same wlan1 interface of the AP?

Come on guys… please for your lights!
