Hi,

I have a requirement as follows.

I have one ubuntu ( 11.10 ) machine having two ethernet ports and one eth0 - Connected to internet and eth1 connected to private network .
I have n number of IP phones and client machines in my private network .

My requirement is to configure my ubuntu as gateway server for providing internet to my private network. I could configure DHCP service on Ubuntu which is capable of providing IP,netmask,gateway and name server information to client.

Can any one please tell me the steps for configuring gateway server .

Thanks in advance.

This is way to much to explain in a forum post..

I would suggest reading

and then ask specific questions for issues you dont understand...
