We have an on-site VPN between a USG Flex500 and Flex50. It seems that everything is fine, it works, but something happens, the connection is alive, but there is no traffic in it. We disable and re-enable the firewall rules (policy control) on the Flex500 and it works for a while and then it happens again.

    Looks like you need someone from Zyxel Support to have a look at your VPN logs, maybe even debug logs if necessary.
