DHCP Setup Help !!! not responding to DHCP requests!
Posted on 2007-10-08
My connection is setup like this
T1 -> Cisco 1721 router -> switch -> server, workstations, net printers..etc.
AD is installed, and dcpromo'd. DNS configured correctly.
now i want to run DHCP on this server, the DHCP on the cisco router is turned off. (we were using the DSL router as DHCP before)
We are assigned static IPs from our ISP, like below
usable IP range: 184.108.40.206 - 220.127.116.11
Broadcast address: 18.104.22.168
router IP 22.214.171.124
subnet mask: 255.255.255.248
DNS 1: 126.96.36.199
DNS 2: 188.8.131.52
1st NIC is setup as static IP like above, I assigned 184.108.40.206 to the server, 2nd NIC is disabled for now.
so I setup the DNS on the server, and in the NIC properties, DNS is setup to the server IP, and in DNS forwarder i set it to forward all queries to our ISP DNS 220.127.116.11 /3
the server has access to internet and everything.
DHCP is setup like this
Start IP: 192.168.0.14
End Ip : 192.168.0.47
Scope Option>Router> 18.104.22.168 (T1 router)
Scope Option>DNS Server> 22.214.171.124 /3
while on the workstations, they are not getting any DHCP response at all.
Did i assign wrong IPs in that DHCP table?
I do not want to assign real IPs to workstations, I want to assign private block of IPs to the internal machines, like how it was before with the DSL router.
Can anyone point me to the right direction? Please help!!
