Mmmh... i suppose this was a solution, but too expensive... (in Italy
there's no flat ISDN access).

?! I suppose that when a cipe dynamic peer comes up, and say to static
peer ``hi, i'm X.Y.Z.W:P'', the static one keep talking to X.Y.Z.W:P
until some other greeting arrived.
If i've understood well, when the static peer expire the key, they
doesn't even try to contact dynamic peer, so link cant work. Right?!

?! I've not understood this... i've forgot to say that the local have
static ip, and the rmote has dynamic ip... so this complicate the
things... i've just put in ip-up some pings to (static) peers to force
a key exchange but i cannot do this without keep the connection up...
