There are two settings to be provided in the Router:
~ LAN to WAN: You want to control the traffic flow from the local network to the outside
world. e.g., you have a FTP server inside the local network and you want to have a limited
traffic rate controlled by the QoS policy. So, you need to add a policy with LAN to WAN
direction setting.
~ WAN to LAN: Control Traffic flow from the WAN to LAN. The connection maybe either
issued from LAN to WAN or WAN to LAN.)
Protocol: The Protocol will be controlled. For GRE protocol, there is no need to specify
the IP addresses or Application ports in this page. For other protocols, at least one value
shall be given.
~ ANY: No protocol type is specified.
~ TCP
~ UDP
~ ICMP
~ GRE: For PPTP VPN Connections.
DSCP Marking: Differentiated Services Code Point (DSCP), it is the first 6 bits in the ToS
byte. DSCP Marking allows users to classify traffic based on DSCP value and send packets
to next Router.
Note: To be sure the router(s) in the backbones network have the capability in executing and
checking the DSCP through-out the QoS network.
