Sophos Firewall: v18.5 MR1: Feedback and experiences

Hi foks

more experimentation. I disabled the default SSL/TLS inspection rule and created my own with decrypt enabled.

What logviewer shows is the exception list is still active even though the description of the list says for the default SSL/TLS rule. So how do you disable the default exception list? Also somewhere there is hidden an SSL/TLS rule 0 which is used for Sophos software updates to at least APX120 connected to CM.

Ian

Do you mean the Exception List within Web and not the local TLS List? Because the exception List will be used all the time. 

The description advised the default rule, not user defined rules.

Ian

You can remove the managed TLS List from the Rule: 

But the rule was disabled and the exception list was still applied to my new rule.

Ian

The Exclusion Website Rule on ID1 is always enable. I am not able to understand, what you mean? Can you show us a screenshot? 

That is exactly what I am talking about, you can disable web exceptions but not SSL/TLS exceptions.Ian

You can turn It off if you want to.

Sorry,,if you want to experiment without having the default exception list get in the road, you cannot turn it off. Turn it off disables SSL/TLS as well as the exception list.

Ian

You can turn off the default exclusion list since v18 EAP, even the managed local TLS exclusion list can be disabled.

The only exclusion list you can't turn off is the hidden rule #0 for system exclusions. (Sophos domains.)

DPI Engine will still work fine.

Hi Prism,

there is nowhere to disable the default ssl/tls exception list even if you do not select in your rule. Whereas in the web exception list you can disable an exception list.

Ian

You're looking at the wrong place.

The picture you just sent are just the URL Groups that are use on the TLS exception, not the exceptions itself.

Look again on the picture I've sent above.

all that does is disable the rule not the exception list. If you review the web exception lists there are disable buttons, but the TLS list does not have the same feature.

Ian

Sorry Ian, i am still confused, what you mean. The URL Lists, you linked are used as "Websites" in TLS/SSL DPI. You cannot remove the Local URL List. But remove all others. You can create your own List and rules. 

What exactly do you want to disable and why? 

I was trying to test my own ssl/tls rule to see if I could replace the web proxy in some of my rules but failed because of the default list.
