Configure dhclient to check value of DHCP options

[Jon Smaller]

Hi Alan,

That approach would work but would involve having firewall rules on  
each of the boxes ... And for different installations of our  
monitoring solution, the main DHCP server would have different ip  
addresses, thus increasing the configuration complexity of the  
individual boxes (I intend to have a large number of these monitoring  
boxes in the field).

Also were the IP/NIC of the main server to change, then we would have  
to manually reconfigure the firewall rules on each of these boxes,  
which could number in the hundreds.

Jon
