Всем добрый день
Есть код TDI драйвера :

/* this completion routine queries address and port from address object */

Проблема в том, что при установке соединения код:

    KdPrint(("[tdi_fw] tdi_create_addrobj_complete2: address: %u:%u\n", 
         ntohl(((TDI_ADDRESS_IP *)(addr->Address))->in_addr),
         ntohs(((TDI_ADDRESS_IP *)(addr->Address))->sin_port)));

дает in_addr равный 0, а порт достоверный. Я смотрел процесс в TCPView, и in_addr должен совпадать с моим локальным IP. В чем может быть проблема?
