Note: The SonicWALL does not relay DNS settings to the LAN; you must enable and
configure the SonicWALL'DHCP server or manually configure DNS settings on your
computers to obtain DNS name resolution.
In the WAN/DMZ Settings section of Network, you can Renew and Release the
SonicWALL WAN IP (NAT Public) Address lease. When you click on Renew, the SonicWALL
renews the IP address used for the WAN IP address. Click Release, and the lease is
released with the DHCP server.
NAT with PPPoE Configuration
The SonicWALL can use Point-to-Point Protocol over Ethernet to connect to the Internet. If
your ISP requires the installation of desktop software and user name and password
authentication to access the Internet, enable NAT with PPPoE.
To configure NAT with PPPoE, complete the following instructions.
1. Select NAT with PPPoE from the Network Addressing Mode menu.
2. Enter a unique IP address from your LAN address range in the SonicWALL LAN IP
Address field. The SonicWALL LAN IP Address is the address assigned to the
SonicWALL LAN port and is used for management of the SonicWALL.
3. Enter your network subnet mask in the LAN Subnet Mask field. The LAN Subnet
Mask tells your SonicWALL which IP addresses are on your LAN. Use the default value,
"255.255.255.0", if there are less than 254 computers on your LAN.
