Good Afternoon ClearOS,
Our current wired setup devices on 10.10.1.X
Our current wireless setup devices on 10.10.2.X

Both networks can ping each other, however, certain devices are unable to communicate via broadcast. (ChromeCast, Apple TV, etc)

Does anyone have any suggestions?

Thank you kindly,

-Luis

    Update:
    We resolved this by changing Class to a Class B network; reconfiguring the network and all...fun.

    Thanks for the help provided.

    Only subnet-subnet traffic is allowed between subnets and I am not sure how to allow unicast and multicast. One way round this is to bridge your two LAN interfaces but then they will share a single subnet. You could try something in iptables. Perhaps something like:
    iptables -I FORWARD ! -i ethX ! -o ethX -j ACCEPT
    Please try this at the command line first. ethX is your WAN interface and the ! may go after the -i and -o. I have a (very) strong suspicion this will not work.

    I think you need to google something like "forward multicast between subnets linux" which leads to references like this and perhaps packages mrouted.

    [edit]
    Sorry posts crossed.

    and btw changing the subnet to 254 won't work either because that puts both interfaces on the same subnet. The only way to do that is to bridge the interfaces.

    Thanks Tim, you're correct, we are using 255.255.255.0 for our netmask.
    One interface connects to our wireless devices, while the other one connects to our wired devices.

    Which netmask should have the 254 subnet?

    What subnet masks are you using? 255.255.255.0

    You need to change your subnet mask to include both segments to see broadcast traffic
