I have a dhcp on my Linux box running Edubuntu for my thin clients and an Apple Exstream wireless airport that I want to use for connecting all other Macs on my network. How can I do this?

My setup is
- LTSP box connected to the internet directly and on another nic to a 16 port switch
- Apple Airport Exstream connected via wan to the internet and via port 1 to the same 16 port switch
- Macs and LTSP sharing services and having conflicts with dhcp.

Thanks for listening,
