What's the network number on the Ethernet side? Is it a legitimate network number assigned by ARIN, your Internet Service Proivder, or some other authortity? If yes, it could work. If not, it won't work. Private addresses aren't routable on the Internet. If you are using some address that isn't private but wasn't assigned, you won't receive any packets. > s0 is connected to t1 internet line(ip: 64.4.4.4) Have you arranged with your Internet provider to advertise your network number so the rest of the Internet can send packets to your users? > > I simply want to give these users internet access.

IP addresses are end-to-end. If a PC on your network has an IP addres of say 10.0.0.1 and wants to reach say www.priscilla.com (which has a global Internet-routable address), and you don't do NAT, the packets from the PC will die at your router (if properly configured) or the next router. If the PC does have a legitimate routable address, its packets will get out, but www.priscilla.com needs to know how to send packets back to the PC, which it can't do unless your Internet service provider has advertised to the Internet how to reach your network.
