to allow URLs with wildcard destiations on non web browsing ports

Hello Checkmates! Anyone can help out how to allow following wildcard URLs on non web browsing traffic on R81.10? Can't use Non-FQDN object due to reverse DNS is not working and updatable object also not available. Destination *.bam.nr-data.net *.apse2.pure.cloud Ports/Services TCP/UDP: 3478 (STUN) TCP/UDP: 19302 (STUN) UDP 16384-32768 (SRTP/TURN) TCP: 8191 (HTTPS)

For things that are actually HTTPS, you need to ensure the ports are configured here:

However, you list several things that aren't HTTPS.
If the gateway is in the path between the client and their configured DNS server, Passive DNS Learning can help with non-FQDN Domain Objects.

If the vendor in question provides a list of IPs in JSON or a flat file form, upgrade to R81.20 and use a Network Feed object.

New_application-Site.pngThanks for the updates.

we do use many Custom Application/site allowing Web Browsing Servers. 

If we add more ports under Application Control Web Browsing Services, the other Custom Applications/Sites will be affected by this and it end up allow extra ports for other  Custom Applications/Sites which we don't want to.

Hope that if there is an option to choose other then Web Browsing under New Application/Site.

If it's not actually web browsing then you should be using an FQDN object as the destination and then the services as normal.

Yes, this is a global setting that affects all such Custom Application/Sites, which are primarily for applications that use HTTP/HTTPS.
For application that speak other protocols, you will need to use either a Domain Object or possibly a Network Feed (in R81.20), though I'm double checking it will work for this use case (e.g. including *.example.com).

I double checked with R&D and confirmed that wildcards can be used in entries listed there (provided it’s something like *.example.com and not www.*.com, I.e. the wildcard is first).
This also requires Passive DNS Learning to be enabled, which requires the gateway to see all the DNS requests from the clients: https://support.checkpoint.com/results/sk/sk161612

100% you can do that. Just add more services where Phoneboy mentioned and you can do what I always do...so say you wish to block anything youtube, just add *youtube*

Hope that helps.
