One more thing as an addendum to the last post. If I run tcpdump on the
machine on the remote side of the vpn I never see the echo request come

As I see it, the problem is either on the FC3 machine not properly
routing, or the VPN device is not properly handling it. Not sure how to
really determine which is the culprit.
