A broadcast domain is the layer 2 segregation of the network. If you're not using VLANs, and have one switch, you have one broadcast domain. The broadcast address is different, but those broadcasts all go to every device. In the case of buggy phone firmware maybe they don't listen to the broadcast address on other subnets, but they're still receiving those broadcasts and still on the same broadcast domain. http://en.wikipedia.org/wiki/Broadcast_domain --------------------------------------------------------------------- To unsubscribe, e-mail: support-unsubscr...@pfsense.com For additional commands, e-mail: support-h...@pfsense.com Commercial support available - https://portal.pfsense.org
