Aye, that's the rub. Most hosts are in dynamic address space,
and anything involving DNS will not fly.

It is certainly a problem, but you can get around it partially even if your IP
address is dynamically assigned:


You do need to use a dynamic DNS server to handle your keys, but there
are lots of those, and many do provide that service.

Also, this is limited to "initiate-only" IPsec; it does not handle incoming
connections. However, that may be enough for many client machines that live
in dynamic address space.
