Hi,

If you want to run multiple endpoints behind the same NAT,
you can:

1. assign unique call signal ports to each endpoint, and
   forward them across the NAT.  You may need to set up
   forwarding for RTP, too.  Or,

2. Run another GK at the NAT location.  This is easiest
   if you run it on the NAT box, but it can also work if
   the gk has only a private address (2.2.x may still
   have a bug associated with being behind a NAT).  Or,

3. Some endpoints have their own NAT traversal logic, and
   can be configured to act as if they are on the public IP.
   Sorry, I don't know if GnomeMeeting or MyPhone can work
   with gnugk in this way.  Or,

4. Some NATs are H.323-aware, and will properly proxy for
   you.  However, many of those won't work for multiple
   endpoints.
