Once you have entered all applicable information, click Add
Outbound Policy
. From the subsequent page that displays, you

can move or edit this policy using the Up, Dn (short for Down),
Edit, and Delete buttons. Important: The firewall applies

outbound policies in a top-down order according to their location

in the policy table page. Once you have created all your rules, or
policies, use the Up and Dn buttons to put them in order in the

table from top to bottom. You can always add an All policy at the

bottom of the list, so that if there are any packets that don’t match

any of the above policies in the list, they will be denied (if you set

up Deny All), or permitted (if you set up Allow All).
