Standard Configuration - Dell SonicWALL GX250 Manual

DNS Settings
• DNS Servers
DNS Servers, or Domain Name Servers, are used by the SonicWALL for diagnostic
tests with the DNS Lookup Tool, and for upgrade and registration functionality.
DNS Server addresses should be assigned by your ISP.
If you select NAT with DHCP Client or NAT with PPPoE mode, the DNS Server
addresses is assigned automatically.
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 computer
DNS settings to obtain DNS name resolution.

Standard Configuration

If your ISP provided you with enough IP addresses for all the computers and network
devices on your LAN, enable Standard mode.
To configure Standard addressing mode, complete the following instructions.
1. Select Standard from the Network Addressing Mode menu. Because
NAT is disabled, you need to assign valid IP addresses to all computers
and network devices on your LAN.
2. Enter a unique, valid 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's subnet mask in the LAN Subnet Mask field. The LAN Sub-
net Mask tells your SonicWALL which IP addresses are on your LAN. The default
value, "255.255.255.0", supports up to 254 IP addresses.
4. Enter your WAN router or default gateway address in the WAN Gateway (Rout-
er) Address field. Your router is the device that connects your network to the In-
ternet. If you use Cable or DSL, your WAN router may be located at your ISP.
5. Enter your DNS server IP address(es) in the DNS Servers field. The SonicWALL
uses the DNS servers for diagnostic tests and for upgrade and registration func-
tionality.
6. 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.
