1. A wireless router supporting communications between a wireless client and a wireline network comprising:

  • a wireless interface coupled to a server and possessing a wireless transceiver;

    said wireline network coupled to said server via a wireline communications port;

    at least one computer operating said server based upon a program system comprising program steps residing in memory accessibly coupled with said computer;

    wherein said program system is comprised of the program steps of;

    coupling said wireless interface to said wireline network via said wireline communications port as a server device with a network service address;

    enabling address translation on said server to include said server device with said network service address;

    adding a network route for said wireless interface on said server for said server device with said network service address; and

    making said wireless interface available to at least one wireless client communicating via said wireless coupling as a gateway to communicate on said wireline network;

    a wireless client communicating via said wireless coupling based upon a login protocol accessing a client authorization list to create an authorized client; and

    said authorized client communicating via said wireless coupling using said network route to communicate with said wireline network via said wireline communications port;

    wherein the program step making said wireless interface available to said wireless client is further comprised of the program steps of;

    said wireless transceiver receiving a first message including a destination from said wireless client to create a first received message including said received destination at said wireless transceiver;

    said wireless transceiver transmitting a second wireless destined message to said wireless client;

    transmitting said first wireline network destined message including said wireline address via said wireline communications port; and

    receiving a second wireline network message including a destination containing said network service address to create a second wireline network message including said destination containing said network service address to said server device;

    wherein the program step enabling address translation on said server is further comprised of the program steps of;

    masquerading said first received message including said received destination to create a first wireline destined message including a first wireline address at said server device; and

    demasquerading a second wireline network message including said destination address containing said network service address to create said second wireline originated message including said destination address containing said network service address;

    wherein the program step adding said network route for said wireless interface on said server is further comprised of the program steps of;

    routing said first wireline destined message at said wireless interface based upon said network route for said server device with said network service address to create a first wireline network destined message including said first wireline address; and

    routing a second wireline originated message including a destination containing said network service address to said server device based upon said network route for said server device with said network service address to create said second wireless destined message to said wireless client;

    wherein said wireless transceiver further supports at least the IEEE802.11b messaging protocol standard in communicating with said wireless client.
