Pix dynamic VPN

Is it possible to have a dynamic site to site vpn tunnel? Plant A uses
static ip addresses. However, plant B is changing its lines and the ISP
cannot supply static IP addresses for the solution chosen (don't ask!).
Instead, the ISP router in plant B is going to have a dynamic public ip and
the pix at plant B is not going to have a public ip address at all. 

 

                        Plant B                                      Plant B
Plant A                                      Plant A

Internet ------> ISP router (dynamic IP) ------> Pix (no public ip)
---------> Pix (Static public IP) ---------> ISP Router (Static public IP)
--------> Internet

 

Any help in this matter would be greatly appreciated.

 

Many thanks,

 

Ian Morgan.
