application based rule

DeepakVerma — Tue, 21 Nov 2023 12:35:52 GMT

Hi All ,
We are planning to implement application based rule like under application tab add required app and under service tab add application default.
However what would be best approach to apply rule where application is showing "incomplete".
Currently we have any any set , so we are planning above steps and don't want to break any on going traffic.

hello,

do you mean that you want to create a rule base using application-id?
if so you can create the traffic and see the kind of app used and than apply it.
please know that there is a "depend on" application list, witch means that if you want to allow lets say 'facebook chat' you need to approve '443, facebook' ect..

if you have more questions feel free.

i read again your post, if the application is incomplete note that it can caused by:
1. deny rule that in an other FW in the flow/ the desired server/client isnt responding with a syn-ack - so that the three-way-handshake isnt complete

2. the three-way-handshake did complete but there ware not enough data to distinguish which app the traffic is intended to.
