As it’s stated here on a web site:
What is DHCP?
DHCP stands for “Dynamic Host Configuration Protocol”.
- What is DHCP’s purpose?
DHCP’s purpose is to enable individual computers on an IP network to extract their configurations from a server (the ‘DHCP server’) or servers, in particular, servers that have no exact information about the individual computers until they request the information. The overall purpose of this is to reduce the work necessary to administer a large IP network. The most significant piece of information distributed in this manner is the IP address.
I have found that things just work “better” if you let the SBS server be the DHCP “hander-outer”, that is, it NOT your Linksys/firewall/router is the one handing out the IP addresses. Again, if you are migrating from peer to peer this is a bit unusual as you’ve been used to having a router that does this function. But IMHO [in my humble opinion] the SBS network works the best [connectcomputer works better, wizards run nicer] if the SBS box is in charge of DHCP and DNS. If you ensure that the router has it’s DHCP function disabled BEFORE you begin to set up the system, the SBS box will automagically set up the DHCP/DNS functions. Go into the webbased interface and adjust the router to have DHCP disabled and then set up your SBS box. It will no longer see another DHCP server and shut it’s own down.
If the SBS box sees any other DHCP server [like your router] on it’s same subnet it will shut it’s own DHCP server down. Don’t forget to run the VPN wizard as I’ve seen my server want to turn RRAS into a DHCP server without running that wizard.
