Im trying to configure a VPN tunnel betwwen a PIX having a static IP and a router having dynamic ip address given by ISP. I have configured a dynamic map on the PIX to accept the connections from the router. The pix is connected to the internet through another ISDN dialup rotuer. My problem is that wehnever i try to configure a tunnel from the router to the pix it is not getting established. but with the same settings if im trying it on the router to whicn the pix is connected i can establish the tunnel.
So is it a problem with the pix that it needs a static ip on the remote peer also or is it a problem with my configuration.
