Comodo Firewall Doesn’t Detect Networks:
When Using Hyper-V External Virtual Switch Adapter
or Hyper-V is Installed But Never Run
Can you reproduce the problem & if so how reliably?:
Twice, both fresh, clean installs; on desktop & laptop
If you can, exact steps to reproduce. If not, exactly what you did & what happened:
1: Install Win10 Pro, enable Hyper-V feature
2: Configure external virtual switch in Hyper-V manager
3: Install Comodo Firewall (CFW)
and
1: Install Win10 Pro on laptop
2: Install CFW
3: CFW detects networks normally
4: Enable Hyper-V in Windows Programs and Features
5: CFW loses Network Zones (except loopback) and no longer detects/creates network zones
One or two sentences explaining what actually happened:
CFW detects networks on Win10 laptop just fine (pre Hyper-V); it does not do so on the desktop, which has Hyper-V bridge on the real network adaptor, and it does not ask or create network zones. Note that the physical network interface is not used by the host machine; the virtual interface is. Installing Hyper-V even without launching it causes issue.
One or two sentences explaining what you expected to happen:
…to be prompted Home/Work/Public network and respective network zone created
If a software compatibility problem have you tried the advice to make programs work with CIS?:
Windows firewall was not disabled during CFW installation; I had to manually disable it
Any software except CIS/OS involved? If so - name, & exact version:
No
Any other information, eg your guess at the cause, how you tried to fix it etc:
Searched for this issue; found the same issue reported on Win8 but was closed due to user not following up: https://forums.comodo.com/resolvedoutdated-issues-cis/hyperv-virtual-switch-not-managed-by-cisv6m133-t89174.0.html;msg671797
Disabled Comodo’s driver on the physical interface; ensured Comodo driver was enabled on virtual interface (it was)
Disabled/Enabled virtual network interface to try to trigger detection
(edit) I had to manually create my home network IP in/out rules, following the laptop (working) rules in order to receive some traffic requests and perhaps filter outgoing requests.
Exact CIS version & configuration:
CFW 8.2.0.4591, sans Chromodo, GeekBuddy
Modules enabled & level. D+/HIPS, Autosandbox/BBlocker, Firewall, & AV:
Unchecked the reduce alerts option during installation; I never got prompted to identify network after restart
Have you made any other changes to the default config? (egs here.):
Yes but I can’t see what the defaults are. Firewall settings options are unchecked except:
- Firewall: safe mode
Traffic: on
Alert timeout: 999
Filter loopback
Have you updated (without uninstall) from CIS 5, 6 or 7?:
No, downloaded/installed a few days go, no program updates (only database)
Have you imported a config from a previous version of CIS:
No, N/A
OS version, SP, 32/64 bit, UAC setting, account type, V.Machine used:
Win10 10130 x64, fresh install from 10130 ISO
UAC OFF, Admin account, on host machine (not VM)
Other security/s’box software a) currently installed b) installed since OS, including initial trial security software included with system:
Malwarebytes Antimalware Premium was already install prior to installing CFW, which is the same configuration on the laptop (without Hyper-V) that doesn’t have this problem
Diagnostics zip is attached
I do not have KillSwitch installed
