IPsec VPN setup ES450

I am attempting to configure an IPsec vpn tunnel between a Juniper ssg520 and an Airlink ES450. I have tried both route based and policy based but I still get the same results. On the Juniper I can see the SA and Link both go active after rebooting the Airlink but shortly after the link goes down. No traffic can pass after configuring the VPN. On the Airlink I reset it to factory defaults and then configured the VPN. Is there anything else I need to configure to allow traffic to pass the VPN tunnel?

Hi,

What exactly are you facing? Are you getting any error or you are not able to pass data?
