multi scope dhcp

[Guest bondo]

I have a 2003 server with all updates, AD, DNS and DHCP running. I created 3

scopes in dhcp that are 192.168.1.0, 2.0 and 3.0. I am using 1 nic with 3

linksys routers. I am able to ping any of the linksys routers and any of the

workstations. The linksys routers all get a dhcp address on the internet

side, but the workstations (xp pro) cannot find the server. All computers can

get on the net, some need to be IP set.

 

server 192.168.2.225

DGateway 192.168.2.1

192.168.2.1 local

router "1" hosts internet w/ nat

 

router "2" 192.168.2.101 intenet side (dhcp)

192.168.1.1 local

 

router "3" 192.168.2.102 internet side (dhcp)

192.168.3.1 local

 

Only the server linksys will hand out an IP.

 

Thanks in advance

RE: multi scope dhcp

 

DHCP runs at layer 2 in the OSI model. As such it only works on a subnet by

its design.

 

To get it to supply addresses to remote subnets from the DHCP server a layer

3 device (your linksys router) needs to have a 'helper address' set to the IP

of your DHCP server. If your router cannot be programmed with helper

addresses, the options are replacing the routers, or providing DHCP servers

on each subnet (or supplying static addresses everywhere!).
