RDP Block Not working

[titusroz03]

Hello All,

I have an issue in my FTD -3105 firewall, RDP block is not working on the firewall .I have ACP configured for any any zone to block TCP-3389 ,also tried a Extended ACL through Flex config but still the same.

There may be a more specific rule above your block rule? You can run system support firewall-engine-debug to confirm which rule traffic traffic matches.

Please provide a screenshot of the Access Control rule you created that does not work.

This is the screenshot and I don't have any rule above this for rdp.

use packet tracer 
I think you use prefillter that bypass the Deny ACP RDP line 
but let check it
