Document: PANA Win32 Notes for IPv6Date    : August 12, 2004 Author  : Victor FajardoContents--------1. Usage Notes2. Implementation NotesUsage Notes-----------The descriptions in this document applies to Windows XPrunning SP1 and above using Advance Networking Pack. For the most part, the Open Diameter PANA library uses MS IPv6 Protocol included in this Pack in an abstracted manner via WinSock version 2. The only operational consideration is that the "Internet Connection Firewall for IPv6" does not automatically open any ports after installation of the Pack(Microsoft Knowledge Base Article 817778). This means that PAA listen operations will be filtered. To view available adapters and thier filtering states:netsh firewall show adapterTo view enabled global portsnetsh firewall show globalportTo enable PAA listen port:netsh firewall set adapter [Adapter Firendly Name] port [PAA Listen Port]=enable protocol=udpFor more information on IPv6 ICF (Internet Connection Firewall) see:http://www.microsoft.com/technet/itsolutions/network/security/ipv6fw/hcfgv601.mspxImplementation Notes--------------------There are some considerations when using WindowsSocket Ver 2 for sending multicast traffic on aUDP socket. These considerations are based onthe difference between WinSock and linux/BSDsockets:a. sockaddr_in6.sin6_scope_id need not be populated   with the proper interface index if IPV6_MULTICAST_IF   is used.b. bind() is required if IPV6_MULTICAST_JOIN is to   be issued.c. Use of GetAdapterAddresses() is prefereble in   retrieving the actual IPv6 based interface   index instead of GetAdaptersInfo().
