Hi Lionel, When NAT exists between PaC and PAA, the IP address and port number of the PaC will simply point to the ones used by NAT. If the IP address and/or port of PaC changes, the IP address and port number attributes will be modified to the new ones based on the IP address update procedure defined in Section 5.6. Said that I don't see a problem with containing IP address and port number in the PANA session attributes.
