How to resolve problem with ike vpn connection after upgrading to firm 5.3?

Hoongks

After upgrading the Flex 500 and Flex 100 to firmware 5.3 I have problem with the ike vpn connection. The site to site VPN connected and data flow from the Flex 500 to the Flex 100 and USG 60, bur data does nor flow from the USG 60 and FLEX 100 to the Flex 500. Data flow in both direct between F100 and USG 60.
Also with the Server-client ike vpn connection, client computers cannot access the any local devices in Flex 500. Also same problem with L2TPclient connections.
SSL VPN connections are working normally.
I do not this problem when I upgrade all the previous versions.

Any log on Flex500 ? 
Did you upgrade the frimware to 5.30

Upgrade about more than a week. From my previous experience, normally take 1 day or 2 to have data flow in both direction for site to site connection after a firmware update. Seem that there is a problem with the server side on the ike or l2tp vpn for the Flex 500. For client from laptop, it show connected but cannot local devices.
