When your SonicWALL has successfully received a DHCP lease, the Network window displays the
SonicWALL WAN IP settings.
•
The Lease Expires value shows when your DHCP lease expires.
• The WAN Gateway (Router) Address, SonicWALL WAN IP (NAT Public) Address, WAN/LAN
Subnet Mask, and DNS Servers are obtained from a DHCP server on the Internet.
Alert Enable and configure the SonicWALL DHCP server or manually configure client DNS settings
to obtain DNS name resolution.
In the WAN/LAN 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 (PPPoE) 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.
