Hello All,

  Well, maybe the subject says all,
  Im running 6.1R acting as NAT, gateway ofcourse, hotspot.
  I have many clients trying to use Vonage, motorola, VoIP devices and
  and few more products.

  The problem is as its described in some websites..
  They can call, receive a call, hear the dailtone but no one can hear the 
other party.

   After researching i found out there is a problem iusing FreeBSD NAT with 
voip protocols.

   i have been advised to use STUN servers, (Simple Traversal of UDP through 
   I found out there is net/stund port and its installed successufly!
   but still lost.

   Can someone kindly and please shade a light on howto
   make voip behind NAT works in my FreeBSD ? im in trouble because of this.

   Thank you.
