Wireless adaptor and method for transmitting and receiving message

A bridge device having a bridge hardware address, the device comprising:

• a first end receiving a first message from a client end and transmitting a second message to the client end once receiving said first message, wherein said first message comprises a first hardware address, a first protocol address, and a second protocol address;
• a table recording said first hardware address and said first protocol address, wherein a transformation between said bridge hardware address and said first hardware address is based on said table;
• and
• a second end transmitting a third message to a server end and receiving a fourth message from the server end once said transmitted third message is received by said server end, wherein said fourth message has the first protocol address and a second hardware address corresponding to said second protocol address,
• wherein when said first message is received by said first end, the third message is generated from the first message by only replacing said first hardware address of the first message by said bridge hardware address, and when said fourth message is received by said second end, said bridge hardware address of the fourth message is replaced by said first hardware address to generate the second message.
