I have a SER server and an * server, both have private addresses and have static nat's on the router to the internet. I have installed STUN (by vovida) on the SER server by giving the SER server a second private address on a sub interface (which is probably not right). I understand I need a public address on the SER box, however is this the correct approach to getting it working for clients behind a router e.g broadband users ?
