2) The description of the policy is optional. In this scenario, we will need to make a policy on
all the SMTP traffic going out from LAN (GE1) to WAN. Since all the traffic should go out
through the WAN Trunk, we need to set our "Incoming" interface to GE1, "Source" subnet to
LAN_subnet, and "Next-Hop" to "Trunk" through the "WAN_Trunk" Interface. And finally
we get to the QoS part of our policy. In this scenario we are going to set 400Kbps for SMTP
traffic. We can assign this policy a relatively high priority (like 100) just in case the bandwidth
is not enough at all but SMTP service can still get more bandwidth than the other type of
network services.
