I'm running pfsense as router and openwrt configured as a dumb AP. I have all devices connecting to the AP in the same VLAN but different IP segment. The topology is like this:
- All-in-one-VLAN: 220.127.116.11/16 with PC assigned to 18.104.22.168/24 and Phones assigned to 22.214.171.124/24, all via mac address allow in DHCP server inside pfsense
I want those devices in the PC IP segment to communicate with each other but not to devices in the Phones segment (trying to emulate a VLAN here, there are several reasons behind it, mainly because of having a poor switch that can't tag VLAN based on mac address).
I have 1 PC and 1 Laptop inside the PC IP segment and 1 IPhone inside the Phones IP segment. I want the PC and Laptop to be able to ping each other but cannot pin the IPhone. When I turned AP isolation on, I cannot ping from my PC to my Laptop.
I have read from the docs that by turning on AP isolation, the packets from my PC will be forwarded to br-interface for it to decide. How can I be sure that br-interface will forward that packet to pfsense and let it route to my Laptop, or will br-interface just drop the packet and not forward it. Is there any way that I can configure openwrt to behave as what I wanted?
Thanks for any of your help!
