  Hi,

 Is there a difference in authenticating a natted or   non-nated UA using 
  www_authen? The reason i'm asking is because
when my UA is directly 
 connected to the internet it authenticates fine but when   NATed I get 
  the following error:

 parse_headers: flags=4096
  0(12877) pre_auth(): Credentials with given realm not found
  0(12877) ---:: didn't authorize
  0(12877) build_auth_hf(): 'WWW-Authenticate: Digest 
 realm="ser.edpnet.net",  
nonce="40f7be4edbd22e214821f2a3937968fc049ae290" '
   0(12877) parse_headers: flags=-1  

 This is normal if it happens only for the first request. Your 
 UA sends the first request without auth. info., the server 
 sends back a negative reply with and auth. header and then 
 your UA is supposed to retry to send the request with proper auth.

 In the future please include network dumps.
