This would indicate that the tunnel isn't forming properly. If you check the system log you should be able to see the log messages to find out why.

Also sometimes web interface shows tunnel as red but tunnel is actually up.

Have seen it usually with Phase 1 (IKE that is on right side).

So if left light is green then tunnel is actually up.

thanks for your all response 

We found solution


We checked the logs and found that the tunnel was down due to reason "Timed out"
- This means we were not getting any reply from the peer end
- We took the captures and logs and confirmed that we were not receiving any replies
- We checked on the peer end firewall and the traffic was getting dropped by policy "Drop Log"
- We created one additional rule above Drop Log to allow the IKE and IPSEC-ESP traffic
- As soon as we did that, we confirmed that the tunnel was up.
