Uplink and downlink definitions in traffic policies of the USG6000 series

Because traffic profiles are referenced by traffic policies, the uplink and downlink in traffic profiles are mapped to directions in traffic policies. It is determined as uplink in a traffic profile if traffic is in the same direction as the traffic policy, and determined as downlink if traffic is in the opposite direction. Before configuring a traffic profile, confirm the uplink and downlink directions based on the actual situation, for example, the traffic of an internal user accessing the external network is uplink traffic, and then map the traffic profile to a traffic policy (source address: user; destination address: external resource address).

For example, to restrict the traffic from the trust zone to the untrust zone, configure traffic control as follows:
�?In the traffic policy, if the source zone is the trust zone and the destination zone is the untrust zone, configure uplink traffic control in the traffic profile (same direction as the traffic policy).
�?In the traffic policy, if the source zone is the untrust zone and the destination zone is the trust zone, configure downlink traffic control in the traffic profile (opposite direction to the traffic policy).
