Hi all,
This is my setup:
pfSense gateway (10.0.63.1) DHCP 10.0.63.100-200.
hAP AC (10.0.63.2)
SSIDs: 2.4g, 5g
I have one Chromecast on each SSID: ‘TV’ on 5g and ‘Home’ on 2.4g. They are both bridged on the hAP AC with a VLAN interface which then sends them to the pfSense box.
I want to have Default Forward disabled for the two wireless interfaces to ensure that all traffic goes via the pfSense firewall.
Although I can ping and establish normal TCP connections with other devices even with Default Forward disabled, which I believe is accomplished due to appropriate configuration of pfSense, multicast packets do not make it back over the originating wireless interface.
For example, if I browse the mDNS domain googlecast on the 5g SSID, I can only see ‘Home’. Vice versa on the 2.4g SSID, I can only see TV!
This seems to suggest that Default Forward is isolating multicast traffic from other peers, but I believe it should be being rebroadcast from the pfSense box. Is this not working because of the bridge configuration I described above? Any advice much appreciated, even if in generic terms due to the problem perhaps needing to be addressed on pfSense.
