In section 6 of pana-ipsec draft:

"        IPv4/IPv6 header (source = PAC-LINK-LOCAL,
                           destination = EP-LINK-LOCAL)
         ESP header
         IPv4/IPv6 header (source = PAC-GLOBAL-ADDR,
                           destination = END-ADDR)
                                                                                
   Following is the packet format on the wire for packets sent from EP
   to PaC:

         IPv4/IPv6 header (source = EP-LINK-LOCAL,
                           destination = PAC-LINK-LOCAL)
         ESP header
         IPv4/IPv6 header (source = END-ADDR,
                           destination = PAC-GLOBAL-ADDR)"

I am not sure what PAC-LINK-LOCAL means in the case of IPv4.  Does it
mean IPv4 link-local address specified in
draft-ietf-zeroconf-ipv4-linklocal?  If so, the IPv4 link-local draft
explcitly says:

   "This
   document does not recommend that Link-Local IPv4 addresses and
   routable addresses be configured simultaneously on the same
   interface."

and I think PAC-GLOBAL-ADDR should be used instead of PAC-LINK-LOCAL
in the case of IPv4.
