+ 0 Votes Give the modem a static IP gechurch January 21, 2013 at 10:39am PST So your modem will still be doing the dialing, but you want the server to do DHCP/DNS? If so what you want to do is: - Set the modem with a static IP (192.168.0.1). - Disabled the DHCP server on the modem. - The modem will still need DNS servers (since it's got a static IP it won't be given the DNS servers your DHCP server is handing out). You can either let the ISP push down the DNS settings, or can use 184.108.40.206/220.127.116.11. - Enable DNS and DHCP on the server. - Configure DHCP to dish out 18.104.22.168 and 22.214.171.124 as DNS servers, and your modem's IP (eg. 192.168.0.1) as the default gateway. - Lastly, make sure 192.168.0.1 and any other static addresses you are using are not in the DHCP address pool.
