LAN Device Configuration 7. To configure Static Devices on the LAN, enter the IP address of the device in the IP Address field
and then enter the Ethernet Addres s of the device in the Ethernet Address field. An exampl e of
a static device is a printer as it cannot obtain an IP lease dynamically. If you do not have Block
traffic through tunnel when IP spoof detected enabled, it is not necessary to enter the Ethernet
address of a device.
8. You must exclude the Static IP addresses from the pool of available IP ad dresses on the DHCP
server so that the DHCP se rver d oes n ot assi gn t hese a ddre sses to DH CP cl ients. You should
also exclude the IP address us ed a s the Relay IP Address. It is recommended to reserve a block
of IP address to use as Relay IP addresses.
9. Select LAN Devices not allowed to obtain IP through SA if there are devices on the LAN that you
do not want to obtain IP addresses through the VPN tunnel, such as children’s computers. You
must know the Ethernet address of the device to configure this setting. The Ethernet address
of a device can be determined by typing ipconfig/all into a Command Prompt window.
Alert You must configure the local DHCP server on the remote SonicWALL to assign IP leases to
these computers.
Alert If a remote site has trouble connecting to a central gateway and obtaining a lease, verify that
Deterministic Network Enhancer (DNE) is not enabled on the remote computer.
Tip If a static LAN IP address is outside of the DHCP scope, routing is possible to this IP, i.e. two
LANs.
