    No big deal. You can use your router to supply addresses or a server, it really depends on the situation. If you have a small SOHO no real reason for a server. We actually had a disscusion on this not too long ago if you search the forum.

    A router would have a dynamic address if you are connecting to an ISP and they won't give you a static address (mainly SOHO enviroments).

    We've used both roles with our routers (Both client and server).

    Currently our routers at our remote sites pass out addresses to their respected sites. But there have been a couple instances where we have had to configure one of the ports to "ip address dhcp" to run as a client and request an IP from the ISP.

    To top it off - we're planning on moving to Windows DHCP for centralized management by changing all the remote sites with the "ip helper-address" (haven't used that before)

    The only issue with this setupo is that if a link to the main site fails you are unable to aquire addresses. I am not a big fan of centralized DHCP servers for remote sites for this reason. I find it much easier to simply run a DHCP server on the router at remote sites. Especialy ones with little IT support.

    True - the only way around that I can think of is to set the lease to a larger number - but we also have redunant links to every site, which would also serve as a safety net.

    Do you know how to configure the IP settings on a host?
