No, it means that your config is bad :-)

It the same as with mediaproxy, it depends on your config.
For nathelper use something like:
  if (nat_uac_test("<flags>")){
        /* ... */
        force_rtp_proxy();
  }

Try with <flags>=3 (tests if the ip in Contact is private, or if the ip
address from which the message was received != ip address in Via).

For mediaproxy use client_nat_test instead of nat_uac_test.
