ICE includes TURN which basically is a endpoint controlled media proxy. In other cases you can get away with the old version of STUN from RFC 3489. Like ICE, this needs to be done by your endpoints but most available endpoints support this. Trouble is, though, that there is no standard way of fixing those cases where STUN alone does not help and you need a media proxy. Which means that if you have control over the NAT, for instance because you know all the NAT boxes involved, you can use STUN if it works for you. But right now the only half-way reliable way to deal with all NAT devices out there is unfortunately nathelper and (rtp/media)proxy. Regards, Martin
