IPS causes Internet access issues

(1/1)

fesarlis:
Hello.
I have a single OPNsense installation which remains untouched over time. All updates are installed.
I hava noticed that over the last few version there are issues with IPS. I have seen other recent post in the forum which mentions there is no internet when IPS is on.

In my case, some sites have issues. Only some (I have a suspicion this is caused also when we try to connect somewhere via FTP but I was not able to confirm it yet).

Let me illustrate with two simple examples:

1. Trying to install Chrome. The setup file tries to download the latest version (obviously) before installing.
When IPS is on it cannot. Switching it off resumes download immediately.
2. Last week I had problems with Anydesk. Switching IPS off resumed access. I have found some rules regarding this program, and I totally understand this could pose a security threat. But I really can't understand why the blocking applies to outbound traffic as well.

I do not mess with all the rulesets, I have scheduled updates and all rules are the default. No custom rules.

Please let me know if you need more information.
Thank you
