Actually, a WAN is a network that spans large geographical areas (example: Dallas, St. Louis, Washington, and Delaware).
The terms WAN, MAN, LAN, and similar ones all refer to the geographic layout of a particularly system. The exact technology used to cover that area is not in any way related to whether it is designated as a WAN, MAN, or LAN. For instance, Ethernet technology used to be pretty much exclusively usable in a LAN design, but now, changes in technology (and cheaper manufacturing costs) allow for a MAN design to use Ethernet technology in its implementation.
As such, WAN, et al are names for the scope of the network, and not its implementation.

The web traffic on port 80 (http on port 80) of the firewall should be allowed from the Internet to the web server. Generally, this is done through the rules configuration.
