Hello,
There is a exchange server in local network and its owa application is reached everywhere.
So, there is a vip configuration and L4 port forwarding(for ex. wantolan: x.x.x.x-->exchangeserverip:443to443)
Firstly, it works good. But, it does not work after 30-40 minutes. When the vip configuration is changed, (for ex. L3 port forwarding: onetoone vip and service 443 in policy ) it work good again. But, it does not work again after 30-40 minutes.
It is bad loop. It can be arp problem.

If the Wan interface is in dynamic mode (DHCP/PPPoE), make sure VIP have "set extip 0.0.0.0" , thanks
