Hi,

I'm currently struggling at the setup that for easier understanding I provided example picture below.

Let's say there's an AP with forwarding between wireless clients disabled. While disabling forwarding is a good thing for security this also means any communication between wireless clients that got IP addresses assigned from within same subnet is not possible. What I'd like to do is to somehow let Layer-3 forwarding through a gateway they all share. This is of course required for firewalling, centralized bandwidth and access control in general.

I don't want PPPoE and /32 tunnels, bridge firewalling at AP is also not favorable.

Is this even theoretically possible or I'm missing something?

Well, seems like I found acceptable solution already. At first look, Proxy-ARP seems to be a solution, but it doesn't work on the same/single interface. So you need what cisco calls - Local Proxy-ARP. MikroTik doesn't really have it by default, but this guy here ingeniously thought how to make one. Gotta love MikroTik and this forum

For those who are interested here are some links that explains the problem in more detail:

Still, if anyone has suggestions or thoughts, you're always welcome to share
