multiple subnets

[Glenn Satchell]

Read the dhcpd.conf man page, look for the section titled EXAMPLES.

You need to create a subnet definition for all three subnets.

subnet 172.17.101.0 netmask 255.255.255.0 {
}
subnet 172.17.30.0 netmask 255.255.255.248 {
}
subnet 10.30.0.0 netmask 255.255.0.0 {
	range 10.30.0.2 10.30.255.254;
	# provide clients with a default route
	option routers 10.30.0.1;
}

On your gateway PC run dhcrelay (check the man page for options, but
usually you only need to specify the IP address or hostname of the
dhcp server as a parameter when you start it.

>Dear all, I'm using the ISC DHCP server V3.0.5 on Linux.I want to make the DHCP 
server work like below. 1. One client(it behaves like a proxy) of 172.17.30.0/29 
acess the DHCP server(172.17.101.1/24,ETH0) 2.This client wants to get the 
ipaddress from DHCP server from the following range(10.30.0.1 10.30.255.254) to 
provide/distribute the ipaddress for the PC under this client.  
PC---+(172.17.30.0/29)proxy client ----> DHCP ser(172.17.101.1/24 ETH0)   
<--------------------------------              10.30.0.1 10.30.255.254  Firstly, 
technically, is it possible to implement on the DHCP server like the above ? If 
possible, would you teach me how to configure or let me know the good free 
document or so ASAP ?
