6. Enter your network's subnet mask in the LAN Subnet Mask field. The LAN Sub-
net Mask tells your SonicWALL which IP addresses are on your LAN. Use the de-
fault value, "255.255.255.0", if there are less than 254 computers on your LAN. If
you have multiple subnets on your network, add the addresses using the Add LAN
Subnet field.
7. Enter the user name provided by your ISP in the User Name field. The user name
identifies the PPPoE client.
8. Enter the password provided by your ISP in the Password field. The password au-
thenticates the PPPoE session. This field is case sensitive.
9. Check the Disconnect after __ Minutes of Inactivity checkbox to automatical-
ly disconnect the PPPoE connection after a specified period of inactivity. Define a
maximum number of minutes of inactivity in the Minutes field. This value may
range from 1 to 99 minutes.
10. If your ISP does not provide you with an IP address, select Obtain IP Address
automatically. If your ISP does provide you with a static ISP address, select Use
the following IP address, and type in the IP address provided into the IP ad-
dress field. Be sure to type it in exactly as it is provided to you.
11. Click the Update button. Once the SonicWALL has been updated, a message con-
firming the update is displayed at the bottom of the browser window. Restart the
SonicWALL for these changes to take effect.
Note: When NAT is enabled, the SonicWALL LAN IP Address should be the gateway
address for computers on the LAN.
When your SonicWALL has successfully established a PPPoE connection, the Network
page displays the SonicWALL WAN IP settings. The WAN Gateway (Router)
Address, SonicWALL WAN IP (NAT Public) Address, WAN/DMZ Subnet Mask,
and DNS Servers are displayed.
Note: The SonicWALL does not relay DNS settings to the LAN; you must enable and
configure the SonicWALL's DHCP server or manually configure your computers' DNS
settings to obtain DNS name resolution.
Restart the SonicWALL
Once the network settings have been updated, the Status bar at the bottom of the
browser window displays "Restart SonicWALL for changes to take effect." Restart the
SonicWALL by clicking Restart. Then click Yes to confirm the restart and send the
restart command to the SonicWALL. The restart may take up to 90 seconds, during
which time the SonicWALL is inaccessible and all network traffic through the
SonicWALL is halted.
Note: If you change the SonicWALL's LAN IP Address, you also need to change the
Management Station's IP address to be in the same subnet as the new LAN IP address.
