According to Wikipedia:

"The same technique is sometimes extended to Transmission Control Protocol (TCP) connections, though with less success because TCP connection streams are controlled by the host OS, not the application, and sequence numbers are selected randomly; thus any NAT device that performs sequence-number checking will not consider the packets to be associated with an existing connection and drop them."
