Right... and line 743,1131 in DHT.cc and 575,586 in Torrent.cc

I modified the is_private function in network.cc to

bool sockaddr_u::is_private() const

{

   if(sa.sa_family==AF_INET)

   {

      unsigned char *a=(unsigned char *)&in.sin_addr;

      return (0==1);

   }

#if INET6

   if(family()==AF_INET6) {

      return IN6_IS_ADDR_SITELOCAL(&in6.sin6_addr)

          || IN6_IS_ADDR_LINKLOCAL(&in6.sin6_addr);

   }

#endif

   return false;

}



and it still didn't work.
