hi every one. I hope someone can provide me a help.

This is my problem :

ver: 9.10
coden: karmic
os: ubuntu

I've configure my PC as DHCP3-server and I have two network cards eth0 and eth1 after i configure it i was not able to connect to the internet.The other LAN card it seems its not picking up the ip address from the source of the internet. my server is connect to a LAN and eth0 is were the source of internet is comming. I wanted my server to be just like a router machine.

-I've configure the interfaces eth1 like this

auto eth1
iface eth1 inet static

-- Ive done this also
default-lease-time 600;
max-lease-time 7200;

option domain-name-servers;
option broadcast-address;
option routers;
option domain-name "mydomain.example";

subnet netmask {
} -----

but after I did this my other LAN CARD cannot detect the internet source, but the other card is working fine my network is able to recieve a ip address. I dont know were i did wrong or lacking a script maybe.
