Is the Thompson Speedtouch 510 v4 single port user gateway an ADSL modem/router or just a modem? Can i connect the gateway to my switch so that the other computers can use my adsl connection or would i have to use windows ICS or some software solution

I just went and googled Thompson Speedtouch 510 v4 and as far as I can tell from your description with just a single port then its a modem. Not sure. Do you still have the box that it came in? If so, what does it say on the outside of it. Lets find out what type of hardware you have first before we move on to how you connect everything up.

In looking at the limited manual that came with it, it actually says router. some of the features inclue: WAN: PPPoE,PPPoA, Ethernet over ATM, IP over ATM LAN: DNS server and proxy, DHCP server and client, UPnP Internet gateway device FORWARDING: IP routing, Internet connection sharing (NAPT), Ethernet bridging, PPTP relay SETUP The setup that I am thinking about is connecting it to my 16 port switch and then having the other machines feed from it. The setup that another co-worker is recommending is to use 2 nic's in the server, connect the router to one of the NIC,s and use the server to act as the DHCP server. The router has a builtin firewall, but probably additional protection will also be needed. Thanks for any suggestion!!!

Does your switch have a uplink?

I don't know if this will all make since but here we go. Allow the router to connect to the internet using its built in PPPoE. Connect the hub to one of the ports on the router and then connect the computers to the hub. Use a crossover cable from the router to the hub and patch cables to the computers. A DSL\Cable router usually has 4 or 8 ports, now one is connected to the hub...use the spare ports and then use the hub for the remaining computers. Furthermore if you have DHCP enabled on the router it will provide private IPs for all the computers connected. If your hub has a uplink port then you don't need a crossover cable if you go from an uplink port on the hub, to a normal port on the other hub/switch, you use a patch cable. Crossover is only used if you dont have uplink ports, or one is already being used.
