System and method for establishing network connection with unknown network and/or user device

A method for providing access to a network utilizing private IP addresses for a user device having an incompatible private IP address, the method comprising:

• intercepting data transmitted by the user device containing the incompatible private IP address;
• modifying the data using a private IP address compatible with the network private IP addresses;
• and
• transmitting the modified data on the network.

A method for providing access to a network utilizing DHCP for a user device configured with a static IP address, the method comprising:

• intercepting packets transmitted by the user device to determine the static IP address;
• transmitting a DHCP request on the network to determine at least one available network IP address;
• modifying the packets transmitted by the user device based on an available IP address;
• and
• transmitting the modified packets on the network to provide network access to the user device.

A method for providing connectivity to a first network for a user device, the user device having a permanent address, the method comprising:

• automatically determining network settings of the first network based on addresses contained in messages transmitted over the first network;
• intercepting user device messages transmitted over the first network without regard to message destination addresses, the user device messages having the permanent address of the user device as a source address;
• and
• modifying incorrectly configured messages transmitted by the user device based on the network settings of the foreign network, wherein modifying incorrectly configured messages transmitted by the user device includes substituting the permanent address of these messages with a router address as the source address, wherein the router address is an address recognized by the foreign network.
