Hi,

There is a description of the PANA session attributes in the section 5.3:

   "PANA SA attributes as well as PANA session attributes are listed
   below:

   PANA Session attributes:

      *  Session Identifier

      *  IP address and UDP port number of the PaC.

      *  IP address and UDP port number of the PAA

      *  Sequence number of the last transmitted request

      *  Sequence number of the last received request

      *  Last transmitted message payload

      *  Retransmission interval

      *  Session lifetime

      *  PANA SA attributes "

A NAT may exist between the PaC and the PAA (that is already covered in section 
6.1). Therefore, the PaC IP address/UDP port number should not be part of the 
PANA session attributes. Instead, we should have the source IP address and the 
UDP source port number of the last PaC-initiated PANA messages (to take into 
account the fact that the PaC may change its IP address cf. section 5.6). I 
don't have any concrete proposal for improving the current text... But maybe it 
is not needed if my comment is not valid at all ;)
