3.1 WAN Interface
WAN (Wide Area Network) is a network connection connecting one or more LANs together over some
distance. For example, the means of connecting two office buildings separated by several kilometers
would be referred to as a WAN connection. The size of a WAN and the number of distinct LANs connected
to a WAN is not limited by any definition. Therefore, the Internet may be called a WAN.
WAN Settings are settings that are used to connect to your ISP (Internet Service Provider). The WAN
settings are provided to you by your ISP and often times referred to as "public settings". Please select the
appropriate option for your specific ISP.
For most users, Internet access is the primary application. R7121-L1/R7141-L1/R7111-L1 supports the
