Firewall rule Facebook / Web URL / App-Filter

Hi,

you need to be using policies which are applied to firewall rules. Are you trying to stop facebook access, also there are default exceptions in there web exceptions for facebook.

the enforcement of policies is via firewall rule using web, application and IPS settings in the Proxy or DPI.

Hi,

if I have understood that correctly, I should use the web filter in the firewall rule and also the application in the firewall rule.

Is that right ???.

ok, thank you, that fits, I can start something with that.

Thanks

I have to ask again

there is only one criterion, either with the IP / subnets or the users that a rule is applied to.

greeting

Its first match. 

OK,
I don't know how to solve the problem. All my rules are not working properly.

Use the policy tester to check, which policy is applied. Then check the affected policy, if all the wanted filters are applied. 

I'm not even sure if it's the WebFilter or the firewall rules.

You need to understand, firewall rules are the way to apply filters. If there is no firewall rule, it will not apply anything. IPS, Web, App control is a filter, which will apply after a firewall rule attached this to the traffic.

Hi,

yes I am very aware of that and I have understood how the principle works.

That's why I keep asking or trying to understand exactly how it works, hence the question when a rule is triggered and applied.

I'll open another topic where I start a call for help.

It's all weird, sometimes it works and sometimes it doesn't. Even with an ANY ANY rule, not everything works.

greeting

Please an expanded copy of your any any rule.

Hi sorry,

but this f .... SSL / TLS on the Android SmartPhones. I looked up in the German description that the SSL / TLS does not work reliably on Android devices.

Man man man, what ***. I always tested the connections with the Android devices, called up websites and various APPs.

Yes, sorry, but why is it that the Android devices cannot cope with the decryption with Google.

What kind of f ...

There is a bug in v18.0.5, try upgrading to v18.5.1 from my testing so far on Apple devices I haven’t had any failures, whereas the previous version I had to stay with the proxy.

Do you have a TLS Decryption Rule created for this device? 

You mean here at this point?

Check your Firewall rule for the device, there is also a option to decrypt the traffic. 

What should I check there?

I don't understand what to check there. ???

I also don't see in the LOG where the problem is, I see the WebFilter appear and are also allowed, but nothing works anyway.

Now I have to go back to ANY ANY, so it can't be that slow.

I look carefully at the one client filtered in the log. The firewall rule and the web filter are all GREEN. No red one among them.

I don't understand where the problem is, for days and hours nothing works, except ANY ANY.

I'm slowly losing my nerve with this nonsense. I've already learned a lot about it, but that can't really work properly.

Thats a rule to select some services.

it doesnt work

You need to understand, if you attach a filter control rule, it can mess up with the traffic. Some devices are not build to work with this. 

Switch everything off in Web filtering and remove the web policy. Try again if it works or not. 

Since I didn't understand, sorry, please explain again in more detail.

Thanks...

Change web policy to allow all.
