I'm trying to find if a firewall rule already existing, with the same name, same configuration, like: localport.

So I use Get-NetFirewallRule to list all rules, but the rules returned do not contain the information of port, also some other information are missing. where can I find all the config of a rule. Below is the attributess returned:

Name
DisplayName
Description
DisplayGroup
Group
Enabled
Profile
Platform
Direction
Action
EdgeTraversalPolicy
LooseSourceMapping
LocalOnlyMapping
Owner
PrimaryStatus
Status
EnforcementStatus
PolicyStoreSource
PolicyStoreSourceType

In order to find the port numbers that are already in the firewall rules, you can use a different cmdlet Get-NetFirewallPortFilter.

(Info)

Use Get-NetFirewallRule to filter which subset of rules you want to look at and pipe it to the above cmdlet. eg.:

Get-NetFirewallRule -DisplayName "SQL Broker Service" | Get-NetFirewallPortFilter

Sounds like the property you are after is localport.
