PIX VPN with dynamically assigned IP address

I have a Cisco PIX (PIX-1, in the following) which has to establish a VPN connection to another PIX (PIX-2) using a preshared key.
It works fine but, since the PIX-1 is connected to the internet using an ADSL (PPPoE) connection with a dinamically assigned IP address, the VPN can't work properly when an IP reassignement occurs.
A manual reconfiguration of IPSEC on PIX-1 is then necessary in order to establish a new connection with the proper parameters (no changes are needed on PIX-2, instead).

Is it possible to make PIX-1 performing such reconfiguration (i.e. recreation of the IPSEC SA with the new IP address) automatically, each time a dynamic IP reassignement occurs?

Hi davidey,
If PIX-1 only needs to establish the VPN (i.e the VPN does not need to be established by PIX-2 when a computer at that location wants to talk) then you can set it up as a EasyVPN client.
