`1. A server for use with a network to provide access to a
`mobile computer configured for a different network without
`reconfiguring the mobile computer through hardware or
`soxware, the server comprising:
`1) a registraJon module to register the mobile computer to
`access the network;
`2) a registraJon driver to assign internet protocol (IP)
`addresses and maintain and access addressing informaJon
`including IP addresses and media access control (MAC)
`addresses, wherein the assigned IP address assigned to the
`computer is mapped to the MAC address of the mobile
`computer;
`3) an internal interface to connect the server to the
`computer;
`4) an external interface to connect the server to the network;
`5) a packet driver module to perform network address
`translaJon (NAT) between the assigned IP address and a
`configured IP address of the mobile computer at the internal
`interface;
`6) a packet filter that permits transmission of packets to and
`from the external interface based on registraJon status;
`7) a dynamic host configuraJon protocol(DHCP) module to
`service DHCP request based on assigned IP address; and
`8) an address resoluJon protocol (ARP) module that uses the
`registraJon driver to provide MAC address for an assigned IP
`address so that the mobile computer configured for a
`different network is provided with access to the network
`without reconfiguring the mobile computer through
`hardware or soxware.
