All responses are welcomed!

I have some remote sites that are getting access to the Internet via a
Netopia router (ver. 4.11), obtaining a dynamic IP. I'm trying to set
up a VPN to my Netscreen 100 (ver. 4.0.0r.8.0), which has a static IP,
via IKE. Searching both the Netopia and Netscreen sites, I believe I
have configured both boxes correctly but can not get the two to
communicate. Has anyone attempted this type of setup before? If so,
were you successful? Any advise on getting these to boxes to play
together would be very appreciated!

Thanks in advance,

Steve
