Hey there,

 

if you want to stay at FortiOS 5.6 please try the latest version (5.6.5)

there are many fixed issues.

when you say no utm features enabled then you mean also no proxy options enabled?

By no UTM I mean all UTM features are unchecked in the policy created for Internet connectivity. It is set in basic NAT mode with a static route to the gateway of the provider.

Check the interface for errors from the cli.

Also best practice is to force the speed and duplex and not use auto on the ingress/egress ports to outside providers.
