Configuring multiple default gateways on DHCP server
Posted on 2011-10-26
I have DHCP running on my Windows Server 2008 R2 domain controller. It is currently handing out a default gateway, which is my local router. I have another site, connected to my main site by a T1 connection, that I would like to add to my domain. They have their own internet connection (router); they only connect to the main site to access an IBM server running our financial system. The remote site is on the same subnet as the main site (mainly to eliminate the need for another server), and I would like take them off of static addressing and put them on DHCP. The issue I am foreseeing is that I do not want to send remote internet traffic through the small T1 line to the router in the main building. I know there is a way to configure additional gateways on a DHCP server and order them by preference. How does the server/client decide which one to use? Is it just by availability, or is it judged perhaps by a metric? Point is, I would like to send DHCP through the T1 line, but have internet traffic stay local. Is there a way to configure this or am I better off installing a remote DHCP server?
