[Serusers] nathelper question

[jimmy way]

Hi all,
  First ping_nated_only param of nathelper is
unusable. and nathelper function is_nated? is unusable
too. I used testing src_ip of NAT address instead of
it.
  natping function is no effect for cisco route(cisco
2622 with ios 12.2T)? I used the function but fail at
last. The NAT mirror lost at last. I only can use
register in 900 seconds.
And I even don't know if it's useful.
