  • Hi,

    So you don’t have a NAT device and want to use windows server 2003 RAS role as a NAT?

    Windows server 2003 could work as NAT.

    But I’m a bit curious with your gateway. I guess windows server 2003 connect to internet via your default gateway. If so ICS is another solution:

    At last, buy a wireless router could be a better solution.

    Hope this helps.

  • Hello,

    Sorry for the delay. Since the IP address come from a DHCP server, how did you configure your DHCP.

    DHCP option 003 router specify your default gateway.

    So please check your configuration.

    Hope this helps.

  • In the scope options form of the the DHCP server settings  003 is the Default gateway, use the ip address from the router in your network.
