Wireless Connection Problem

ceceghini

Hi,
I have a router with 3 pfsense configured networks

WAN for connect to internet
LAN cable (used for server)
WIRELESS (used by all my pc)

All PC (both LAN and WIRELESS) are able to connect to internet
All PC (LAN) are able to connect to PC (WIRELESS) .. ping ssh
All PC (WIRELESS) are able to connect to PC (LAN)
The PC (WIRELESS) CAN NOT CONNECTED to PC (WIRELESS)

Apparently it is a problem of ARP but I can not figure out where he is the problem

You know you help me?
Thanks,cesare
