how to get blocked traffic information from LAN Traffic.

hello ,

i am using srx 340 in production and have limited traffic open for internal users like pop smtp 80 and 443..

now there is app called anydesk for remote support. this is application is not working i already opened port 80 and 443 as suggested by support team of anydesk. if i creat policy with any any source and destination it start work but this is not possible to open all port for internal traffic.

now i wanted to trace what traffic hiting to srx from local traffic which is notpermitted and blocked by firewall.
