CIS 5.12 and 6.0 cannot find & firewall my PPPoE Internet Connection [V6][M203]


  1. What you did: updated CIS 5.10 to 5.12 and as I found this Bug I clean Installed CIS 6.0
  2. What actually happened or you actually saw: CIS 5.12 & 6.0 Both Couldn’t detect my Internet connection and transfers. as I activated Block all in firewall nothing happend too.
  3. What you expected to happen or see: as I activated Block all in firewall nothing happend too. Killswitch shows all net activities but firewall traffic pane shows only zero send and recieve.
  4. How you tried to fix it & what happened: I removed my lan Driver and installed it again. I did it with Router too. I tried differen Ip’s for my network and router.
  5. If a software compatibility problem have U tried the compatibility fixes (link in format)?: I did not install any new software.
  6. Details & exact version of any software (execpt CIS) involved (with download link unless malware):
  7. Whether you can make the problem happen again, and if so precise steps to make it happen:
  8. Any other information : Since I updated from ver.5.10 to latest CIS 5.12.256249 The problem began.
    I thought ver. 6.0 maybe will work, but after installation of CIS 6.0 I have the same Problem.
    I use a single pc with lan and ADSL Router (Tplink wired td-8811 adsl Router) connected to it.
    my Adsl Router ip is set to and Pc local area connection is
    Firewall has detected as Network zone, but It doesn’t show or block the activity through this Ip.

I have set my router to PPP over Ethernet (PPPoE) with username and password configured in the router.
When I change the connection type to bridging, the Firewall works fine and detects my internet connection, But I get some Remote Ip attacks with different Ips, I can not block. So I prefer Use PPPoE connection type.
I did changes, reinstalls, resets and so… But nothing helped.

Version 5.12 fixed an issue with pppoe connections on Windows 8. In case you would like to try get 5.12 from here.

Can you show a screenshot of your Global Rules and Firewall logs? That may help to get a bit more of an idea what is going on.

What does the application ida.exe do? What is the model and make of your ADSL router?

Hi Eric,
Those links redirect to V6 download.
Older versions found in the link below.

Thanks for the screenshots. Can you change the block rule at the bottom of Global Rules to block and log? That way we will actually see what the firewall blocks.

Can you make sure that Block Fragmented IP diagrams and Do Protocol Analysis are not enabled? They can be found under Firewall Settings.

I tried to download your report but it seems I need to sign up for that service. Is that correct? It is zipped so you can also attach it to a post instead. To attach a file push the reply button. Or when using the Quick reply type some text and push the preview button.

Underneath the text box click on Additional options. Push the Choose button and navigate to the file and select it. When you want to post more images click on the more attachments link.

When done typing push the Post or Preview button.

The CIS report shows nothing out of the ordinary. I think we may be looking at a bug and since we are in the bug report section please make a bug report following these guidelines.

In your situation it may be better to start a new topic from scratch.

I have updated this topic with all needed Informations for Bug inspection.
Hope someone takes care of it.

Mod edit: Fixed the colour tags, Captainsticks.

Many thanks for all this information, which is much appreciated.

We will of course forward it, but could you edit your first post to use section A of the format please, and state what your config is in question one of section C.

Many thanks
