Because I am using VLANs to segment the three networks, for security reasons, it is simpler to allow the router to do the DHCP. This allows the router to control all the ACLs since it knows about the internal network from the DMZ from the guest network. This is the reason for using the router for the DHCP.

Subject: Re: Bind9 and a Cisco router
Your better at this then I am so I am curious... why not have the bind server do DHCP?

I have a Cisco 881W router and it does the DHCP to all my VLANs. I need to configure Bind9 for DDNS so that my windows systems can be pinged by name by all systems. Since DHCP is coming from the router I have no idea how to configure Bind to use an external DHCP server for DDNS. Does anyone know where I might find more information on this, or has someone already done this and knows how I need to configure Bind9.
I used to do DDNS with Bind9 and DHCP on my Linux system, but the new network configuration will not support that architecture so I have to come up with a different way to make this work.
Thank You,
