Thank you for the post @Toufik Basically by default all communication that Firewall will initiate will be over management interface. In the case you for what ever reason can't use management interface, you can change all services to communicate via data plane interface instead of management interface. You can also do it selectively based on service you want to communicate over data plane interface. Here is KB: https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000ClGJCA0 In the case of Active/Standby HA you will come across an issue when standby Firewall will not be able to use data plane interfaces (Depending on HA configuration interfaces are either shut or suspended), so service route configuration will not work unless Firewall assumes active role or you change it back to use management interface. Connecting management port to switch with dedicated Vlan is the most optimal way. Having management interface on the same subnet as data plane interface is possible and it will work, however I would avoid this security reasons. The first option you mentioned is of course possible to connect management interface directly to your PC, but outside of the lab environment, this is not scalable option. If you need to change management interface IP address from CLI to range for management Vlan, you can do it from CLI: https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000ClN7CAK Kind Regards Pavel
