Correct me if I'm wrong, but this sounds like you've setup the tunnel on the 
Pix as a dynamic tunnel. That means that the remote side MUST initiate the 
connection, as the Pix does not know if the remote's IP address has changed. 
I don't have a pix to play with at the moment, but I think if you set it to 
be a static VPN you may have better luck.

Hope that is of some help...
