[VPN] Netscreen 10 - VPN tunnel drops

[avpn smith]

Hey all,
I setup a VPN between Netscreen-10 and Checkpoint (remote gateway). After I 
reset the Netscreen equipment I am able to connect to the remote gateway and 
other m/cs on that network. But it looks like the tunnel is dropped after a 
while. I then have to reset Netscreen-10.
Any ideas on how I could maintain the VPN for longer periods.
I am a newbie in firewall setup, so any help will be appreciated.

Here are some details after it drops/timesout.

ns10-> get vpn
