Hello, I heard your email-address<well known>  in the net..

I have a question for you

We use Windows NT 3.51 sever as DHCP sever.
We tested DHCP function successfully with  Primary IP address.
But, When We tested this function with Secondary Ip address in our router ehternet port,
this DHCP function does not work.

>We use cisco router rom version 9.01.
>and we configued ip forward-protocol UDP 67 and ip helper-address

the Next is our router's configuration
--------------------------------------------------------
interface Ethernet 7
ip address 166.103.213.193 255.255.255.192 secondary
ip address 166.103.77.193 255.255.255.192
ip helper-address 166.103.78.2
no mop enabled

interface Ethernet 8

ip helper-address 166.103.61.63

!                    
----------------------------------------------------------
Dhcp Server's IP address is 166.103.78.2

after this configuration, Client pc which located in 166.103.78.0 network can get IP 
address from Dhcp server. But Others cannot get IP address....
