DHCP and NAT do not have to be used together. &nbsp;The only time I would recommend using the SonicWALL DHCP option is if you also run a VPN. &nbsp;You will obviously have to set your public servers inside the DMZ with static routes still set.

Hello utahdevildog,<br />
<br />
I would like to use an internal server for DHCP using non-routable IP addresses not the Sonicwall. &nbsp;<br />
<br />
If I do not need to run DHCP and NAT together can I run the Sonicwall in Standard mode using the non-routable IP addresses?<br />
<br />
Thank you,<br />
Theresa

You are still going to want to use NAT. &nbsp;The no-routable IP addresses need to be changed to routable public addresses. &nbsp;NAT performes this function for you.

Hello,<br />
<br />
I am currently running a Sonicwall Pro 100 in Standard mode without utilizing the DMZ or NAT. &nbsp;The only device connected to the WAN link is the router. &nbsp;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. &nbsp;There is a fifth public server that provides DNS - we are our primary and our ISP is secondary. &nbsp;DHCP is handled by an internal server not the Sonicwall and it leases fully-qualified IP addresses.<br />
<br />
The network is a mixed mode with the servers being W2K and NT4. &nbsp;The clients are W95, W98, W2K, WXPro, and various Macintoshes. &nbsp;The printers are accessed via tcp-ip and there is no print server.<br />
<br />
I would like to use the DMZ and NAT along with non-routable IP addresses for our non-public servers, workstations, and printers.<br />
<br />
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?<br />
<br />
Thank you,<br />

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.
