I've setup a DHCP server. Now, if the client falls in the same subnet
as the dhcp server, it's able to fetch an IP and configure its network
as expected. However, if the DHCP server falls in a different subnet,
the client doesn't sense for it. I   want to configure only a single
DHCP server for the whole LAN (across all the subnets)..(I know it's
possible).
Using dhclient -s <dhcpd-server's ip>, and sniffing on the server
using ethereal shows that the dhchpd server does recieve a DHCP
request. But still no response from the dhcpd server. Anyway, I don't
expect the client to be able to specify the source's IP (that's sane,
I guess).

Do I need any specific VLAN configurations to allow this "sensing" of
the DHCP server over the entire network? Or is it that the DHCP server
keeps on making periodic announcements?

DHCP uses broadcast to communinicate with the DHCP server (dest
255.255.255.255, src 0.0.0.0 (unconfigured)) These packets are never
forwarded by a router, so the router needs to relay the packets (this is
different from forwarding, the practice would be better likened to
proxying)
