I am currently running a Sonicwall Pro 100 in Standard mode without utilizing the DMZ or NAT. The only device connected to the WAN link is the router. There are rules to access four servers that provide public access for FTP, Web services, etc. from the Internet. Everything else is denied by a default rule. There is a fifth public server that provides DNS - we are our primary and our ISP is secondary. DHCP is handled by an internal server not the Sonicwall and it leases fully-qualified IP addresses.
The network is a mixed mode with the servers being W2K and NT4. The clients are W95, W98, W2K, WXPro, and various Macintoshes. The printers are accessed via tcp-ip and there is no print server.
I would like to use the DMZ and NAT along with non-routable IP addresses for our non-public servers, workstations, and printers.
I would like DHCP (using non-routable IPs) to be handled by the internal server and not the Sonicwall; is this possible? Or, will this interfere with the ability to use NAT? What would you recommend?
