Group Policy / FW & Traffic Shaping

[Sarv]

Community

If I setup a new Group Policy and select "Custom network firewall & Shaping Rules", are these custom rules merged with the existing "Global" Layer3 rules? or does it ignore those Global rules?

I know for the content filtering section you can select Append, but didn't know what it does for Layer3 rules. 

Thanks

If you configured it for custom, what is configured in the group policy will be used when it is applied to the client or VLAN.

Thank You.

The custom rules within the group policy will overwrite rules configured under "Security & SD-WAN -> Firewall" for clients which have the group policy applied.

Thank you

Custom network firewall and traffic shaping rules are not merged with global firewall rules and are stateless firewall rules that apply on a per-VLAN basis. What ever VLAN is assigned the group policy, it will be enforced with the custom firewall rules you define in your group policy.
