    I currently have a home network for a small business and testing.
    How do I point the DYNDNS IP address from the cable modem to the Mail server (DNS setup correctly).

    I have the following:

    1. Cable modem connected to router
    2. DYNDNS IP Cable modem 10.x.x.254
    3. Router serves and internal network 172.x.x.254
    4. Server off of router at 172.x.x.10 (external access NIC) going to a switch where all other devices are connected to Intranet at 192.x.x.10 (internal NIC) There is an ISA 2004 firewall on the server. (SBS 2003 server)

    The mail server ( points only to the cable modem dynamic IP 10.x.x.254 ---> I need it to point to the server in the network using the ip range 172.x.x.10. This is so I can setup the mail server to send and receive mail. :cry:

    How do I accomplish this?
