I am trying to set up Vaporsec 1.0 to access a Netscreen 25 firewall running 4.0.0r2.0 (Firewall+VPN). I have the tunnel setup and IKE appears to be establishing the tunnel. However, I can not ping anything on the network behind the netscreen and after about 5 minutes the link status changes to down. Anyone have any suggestions on what might be the source of the problem?
