broadcast

I have just setup a new OSX Server in our office and verified that everything is working fine over our wired network (192.168.126.0/24).

The problem that I am having is that our clients (Mac Laptops) are mainly connected via Wireless, which are running on a different subnet (192.168.1.0/24), and the mDNS Broadcast isn't reaching this subnet.

The network configuration is somewhat foreign to myself (I don't manage the network in this location, but as of just recently the servers), however I don't believe there is any firewalls or routing rules between the two subnets which might cause the traffic to be rejected.

I'm wondering if this is simply the mDNS broadcast not able to broadcast over the two different subnets (I'm still reading up on broadcast to understand it more) or there is something else which I might be able to try.
