I left out &quot;forwarding&quot; in the last sentence which should read, &quot;.... DHCP forwarding service installed. . . .&quot;<br />

I left out "forwarding" in the last sentence which should read, ".... DHCP forwarding service installed. . . ."


<div>
ok in that case, is this the way it works ? <br />
<br />
Say a computer in 192.168.20.0/24 networks comes up online. Seeks for DHCP address....now it will sent ARP packing to 192.168.20.0/24 network. Router in 192.168.20.0/24 network sees this broadcast and forwards to DHCP server. DHCP server grants IP and forwards to router which ultimately forwards to workstation..<br />
<br />
and DORA process continues....is it this way ?<br />

That is correct as long as the router on that interface has DHCP Relay enabled &amp;&nbsp;is configured to communicate with the DHCP server.<br />

Hi,<br />
<br />
Lets say,I have multiple networks <br />
<br />
LAN A - 192.168.10.0/24<br />
LAN B - 192.168.20.0/24<br />
LAN C - 192.168.40.0/24<br />
LAN D - 192.168.50.0/24<br />
<br />
<br />
and so on... but would like to have only one DHCP server.<br />
<br />
In that case, do I need to have 5 different interfaces in this DHCP server connected to each LAN ? <br />
or i simply saying , if it is from LAN A, assign IP from this pool in DHCP.conf will work ?<br />
<br />
<br />

DHCP server for multiple networks

The variety of Linux distributions creates myriad issues relating to configuration and operations when computers are networked, not the least of which is the use of various network management applications, some of which are included with specific distributions, while others are standalone applications.
