Configuring a Stateful HA Pair | 31
The Dell SonicWALL NSA 6600 ships with the internal DHCP
server active on the LAN port. However, if a DHCP server is
already active on your LAN, the Dell SonicWALL appliance will
disable its own DHCP server to prevent conflicts.
As shown in the illustration, ports X1 and X0 are preconfigured
as WAN and LAN, respectively. The remaining ports (X2-X17)
can be configured to meet the needs of your network. In the
example diagram, certain interfaces are configured for specific
zones:
• X1—WAN
• X0—LAN
• X8—Wireless LAN
• X16—DMZ
NAT policies allow the flexibility to control Network Address
Translation based on matching combinations of Source IP
address, Destination IP address, and Destination Services.
Policy-based NAT allows you to deploy different types of NAT
simultaneously.
For configuration procedures and information regarding the
different types of NAT policies, such as Many-to-One, One-to-
One, or One-to-Many Load Balancing, refer to the
SonicOS
Administrator’s Guide .
