Both logs report symmetric nat, and in this case ekiga voluntarily 
*prevents* you from registering.  This is probably caused by 5060 being 
blocked.

Are 5063 to 5060 blocked too or not?

I think yes, but I am not sure :(  I have to make tests for that.

I think yes, but I am not sure :(  I have to make tests for that.

So a good idea is to make ekiga use a port different than 5060, as 
written in previous e-mail.
