<p>Hello,</p>
<p>there seems to be something wrong in your config with loading the
nathelper module, can you check if you have proper #!ifdef ...
#!endif blocks?</p>
<p>Try to run it with debug=3 and see if you can spot more hints via
the DEBUG messages printed in the logs...</p>
<p>Cheers,<br>

<p>Hello,</p>
<p>nat_uac_test(...) is allowed in the reply route block.
The error is not about using the function in an invalid
