Hello,

can you add an xlog() message to print branch flags before save("location") and send the output for the two cases?

xlog("message flags are: $mf [$mF]\n");

Also, you may use debugger module with cfgtrace feature to be sure the nat detection actions are executed for both cases.

Cheers,
Daniel
