Quick diagram follows below:
I have two segments on a network, one for data and one for phone.
The phone server has IP forwarding turned on, so I can easily manage phones (10.x.x.x) from the data (192.168.x.x) network. A static route in the router helps facilitate this.
The HP microserver pbx has DHCP service active on the phone network interface. The router performs dhcp on the data network.
The phones are getting dhcp from the router. So, it would seem that the HP microserver is forwarding broadcast traffic. How do I stop this?
---edit---
HP runs centos linux
