Dear Nick,

You could check your IPSec logs to dig down the exact reason due to which
tunnel is dropping. It must be some parameter mismatch. Normally if your
establish tunnel between cisco devices and there is a parameter mismatch,
the tunnel wont establish. but incase of juniper the tunnel will establish
but you will face abnormal behavior.

regards,

Asad
