Abstract: A system and method for disabling header compression during an establishment and configuration of a communication protocol and communication channel between a pair of correspondents. The system comprises an initiating correspondent transmitting at least one PPP negotiation packet having at least one acceptable TCP/IP header compression option type. A software module of a responding correspondent intercepts and examines said at least one PPP negotiation packet before said at least one PPP negotiation packet reaches a PPP layer of the responding correspondent and modifies said acceptable TCP/IP header compression option type to an unacceptable TCP/IP header compression option type and transmits same to said PPP layer of the responding correspondent. The responding correspondent rejects said unacceptable TCP/IP header compression option type. Said software module receiving said modified PPP negotiation packet modifies same to said acceptable TCP/IP header compression option type, and transmitting said PPP negotiation packet to said initiating correspondent.
