Does "Unknown-udp" Appl. allow any UDP Packets?

I did not find any app and would like to allow UDP only.



Hello Hardik,

Just FYI. All applications are not having Decoder. Hence, i don't think it is not necessary to match decoder to identify an Application.



By decoder I mean application signature.

Hi Roman,

Question to your answer is Yes. If you don't have a policy that is not denying "unknown-udp" application, firewall will allow it. In Monitor tab, you will source and destination address and application as "Unknown-UDP". It simply means firewall did not have signature for the packets it was seeing. You can also deny it by denying "unknown-udp" in security policy but is however configurable and is based on your requirement. Hope that helps.
