Set your pre-shared key to either a.) the supernet of the ISP or b.) 0.0.0.0
specifying any host can attach but use a strong pre-shared key.

Is anyone aware of any problems with setting up site to site VPN's with
PIX's where the sites have dynamic IP's.  Situation is I have to link a
bunch of branch offices to main office and all branch offices are DSL or
cable modems that have dynamic and do not have static IP's.  Any problems or
gotcha's that anyone is aware of, one thing I am concerned about is when the
lease expires will the VPN go down and come back up correctly?  How is this
handled?

Anyway thanks in advance for any comments,
