I understand that when using local forwarding mode the client-to-client forwarding on a interface is not set with CAPsMAN, but is controlled by the local CAP.
The manual suggests that client-to-client forwarding needs to be set on the CAP itself, but I can't figure out how to do this. The wireless interface in the CAP (managed by CAPsMAN, local forwarding mode) has default forward checked, but client-to-client forwarding on that interface is still not working.
