begins to count IP addresses against the license, and continues to count new LAN IP addresses
accessing the Internet until the appliance is rebooted.
When a computer or other device connects to the LAN port of the SonicWALL, it is detected via
broadcast and stores the computer or other device IP address in memory. If 5, 10, or 50 IP
addresses have been stored in the SonicWALL, the SonicWALL does not permit any additional
machines to access the Internet. Therefore, the SonicWALL restricts the number of IP addresses on
the LAN, not the number of simultaneous connections to the Internet.
If you have fewer than the maximum number of computers or other devices on your LAN, but it
appears that the IP license limit is exceeded, download a Tech Support Report and review the
devices with IP addresses. Rogue devices such as printers are filling up the SonicWALL IP address
limit. Tech Support Reports are explained in the Tools chapter of this manual.
Additionally, computers with two (2) Network Interface Cards (NIC) can take up two IP addresses.
You must reconfigure your network to avoid these problems by turning off IP forwarding on
Windows

NT or Windows2000

servers using two NICs.
If devices on the LAN receive IP addresses from a DHCP server, see the DHCP chapter of this
manual.
