Setting Policy Precedence2 Traffic rules of the To field3 Traffic rules of the From field4 Firewall action5 Schedule6 Alphanumeric sequence based on policy type7 Alphanumeric sequence based on policy nameComparing policy typePolicy Manager uses these criteria in sequence to compare two policies until it finds that the policies areequal or that one is more detailed than the other:1 An Any policy always has the lowest precedence. For more information about the Any policy, see“Any” on page 379.2 Check the number of TCP 0 (any) or UDP 0 (any) protocols. The policy with the smaller number hashigher precedence.3 Check the number of unique ports for TCP and UDP protocols. The policy with the smaller numberhas higher precedence.4 Count the number of unique ports for TCP and UDP protocols. The policy with the smaller numberhas higher precedence.5 Score the protocols based on their IP protocol value. The policy with the smaller score has higherprecedence.If Policy Manager cannot set the precedence when it compares the policy type, it examines traffic rules.Comparing traffic rulesPolicy Manager uses these criteria in sequence to compare the most general traffic rule of one policywith the most general traffic rule of a second policy. It assigns higher precedence to the policy with themost detailed traffic rule. The list of traffic rules from most detailed to the most general is:1 Host address2 IP address range (smaller than the subnet being compared to)3 Subnet4 IP address range (larger than the subnet being compared to)5 Authentication user6 Authentication group7 Interface, Firebox8 Any-External, Any-Trusted, Any-Optional9 AnyFor example, compare these two policies:HTTP-1From: Trusted, user1HTTP-2From: 10.0.0.1, Any-Trusted“Trusted” is the most general entry for HTTP-1. “Any-Trusted” is the most general entry for HTTP-2.Because “Trusted” is within “Any-Trusted,” HTTP-1 is the more detailed traffic rule. This is correct despitethe fact that HTTP-2 includes an IP address. This is because Policy Manager uses these criteria in158 WatchGuard System Manager

Setting Policy Precedencesequence to compare the most general traffic rule of one policy with the most general traffic rule of asecond policy.If Policy Manager cannot set the precedence when it compares the traffic rules, it examines the firewallactions.Comparing firewall actionsPolicy Manager compares the firewall actions of two policies to set precedence. Precedence of firewallactions from highest to lowest is:1 Denied or Denied (send reset)2 Allowed proxy3 Allowed filterIf Policy Manager cannot set the precedence when it compares the firewall actions, it examines theschedules.Comparing schedulesPolicy Manager compares the schedules of two policies to set precedence. Precedence of schedulesfrom highest to lowest is:1 Always off2 Sometimes on3 Always onIf Policy Manager cannot set the precedence when it compares the schedules, it examines the policynames.Comparing type and namesIf the two policies do not match any other precedence criteria, Policy Manager sorts the policies inalphanumeric sequence. First it uses the policy type. Then it uses the policy name. Because no two policiescan be the same type and have the same name, this is the last criteria for precedence.Setting precedence manuallyTo switch to manual-order mode, select View > Auto-order mode so that the checkmark disappears.You are asked to confirm if you want to switch to auto-order mode.To change the order of policies:• Select the policy whose order you want to change. Click the up or down arrow on the far rightside of the Policy Manager toolbar.or• Select the policy whose order you want to change and drag it to its new location.User Guide 159
