Wireless clients can not access each other

Hi hope you can help me.

I am using a Mikrotik routerboard as a DHCP server. Eth2 is connected to a Ubiquiti high gain sector antenna. Eth3 is connected to a server pc. Ubiquiti en Mikrotik wireless clients connect to the sector antenna. The routerboard, server en sector have static IPs and the wireless clients are using DHCP. The clients can ping the routerboard, sector and server, but the wireless clients can not ping each other en the computers behind the wireless clients can also not ping each other. I have checked and client isolation is disabled on the sector. The Ubiquiti clients can only ping each other. There is also no firewall setup on the Mikrotiks. The clinets are connecting using WDS.

Is there a setting I can change so that the wireless clients PCs can access each other? Or can you suggest the configuration I need setup on the Routerboard en clients?

Kind regards
Johan

Sounds to me like a routing problem. Quick fix would be to put interfaces into a bridge, but don’t, and i repeat. Don’t use it permanent. Routing is the way to go and to get from a bridge network to a routed network is a shlep.
