what do you mean by "there is no nat binding"?  

i have noticed that if you call fix_contact() and then t_replicate(),
t_replicate doesn't replicate the fixed request, but the original one.
perhaps someone can confirm this.  

if true, t_replicate is useless if the client is behind nat and must be
replaced by t_relay or some other function.
